Janome 2030QDC-B vs 4120QDC vs 4120QDC-B Review

Why not treat yourself to a better sewing machine? After all, it will help you finish all those projects you have planned. Let’s review these three models from Janome to see which one suits the way you like to sew.

Janome 2030QDC-B Computerized Quilting and Sewing Machine with Bonus Quilt Kit

The Janome 2030QDC-B is exciting for quilters because it comes with a bonus quilting kit and extension table. And it’s a computerized sewing machine that offers thirty built-in stitches plus three one-step buttonholes.

If you’re a novice, you’ll love features like the start and stop button with the speed control slider. With those aids, you won’t need to master a foot controller.

When you’re ready to start a project, you’ll love the one-hand needle threader and auto-declutch bobbin winder. With the latter, you won’t have to worry about overwinding the bobbins. And the top-loading rotary hook bobbins are straightforward to manage.

If you’re customizing a project, you can adjust the stitch width up to 7mm and the length up to 5mm. Then you can drop the feed dogs for free motion sewing. In fact, the 7-point feed dog system is excellent at handling thick fabrics and layers, too. And you can also set the needle to automatically stop in the up or down position in case you want to rotate your work.

When you finish a seam, you can hit the reverse button to reinforce it by going over it again. Also, sewing collars, sleeves, and skinny jeans are much easier with the removable free arm on the Janome 2030QDC-B.

If you are attending a class or going on a trip, this machine only weighs twelve pounds, making it very portable. And it comes with a wide variety of accessories like a sliding buttonhole foot, an overedge foot, a blind hem foot, and more.

Should you desire more built-in stitches for your crafts, take a look at the Janome 4120QDC reviewed below.

More features of the Janome 2030-QDC-B quilting and sewing machine:

  • Covered by a 25-year warranty on mechanical parts, 2-years on electrical parts, and 1-year free labor
  • Comes with foot controller, power cord, and soft cover, plus other accessories

Where the Janome 2030QDC comes with thirty stitches, the 4120QDC has four times as many. The 120 stitches include a built-in alphabet plus seven one-step buttonholes. And the automatic needle threader makes it a snap to being sewing.

The jam-proof top-loading bobbin is another essential feature. It makes sure you’ll never fret about running off the edge. Plus, you can set the needle to stop in either the up or down position for free motion sewing. The only downside is that there is no automatic thread tension so you’ll have to adjust that manually.

But there are even more advanced features that make sewing a pleasure with the 4120QDC. First, the lock stitch button keeps the machine on track to finish the pattern you begin. In fact, it can remember up to fifty stitch combinations.

Next, the reverse stitch button will reinforce the work you’ve done. And the stop/stop button with the slider speed control let you complete a project without ever needing the foot controller.

Of course, there is a 7-piece feed dog system that can handle layers and thick material without a hiccup. Plus, the extra-high presser foot lifter is just what you need for quilting. And for garment construction, you can sew collars and cuffs in a flash with the free arm.

The only way to improve on the Janome 4120QDC is to add even more accessories to make it even more versatile like the next machine below.

More features of the Janome 4120QDC quilting and sewing machine:

  • Covered by a 25-year warranty on mechanical parts, 2-years on electrical parts, and 1-year free labor
  • Comes with a hard cover and many other accessories

Our final selection is the Janome 4102QDC-B. Many people want to know what the “B” stands for in the product name. It just means that the sewing machine comes with additional accessories or a “bonus” kit. For example, this one has both a quilting kit and an extension table where the base model does not.

The extras include things like a walking foot, a ¼-inch seam foot, a darning foot, a craft foot, a cloth guide, and a quilt guide.

Of course, this sewing machine is as loaded with the same user-friendly features as the 4120QDC we reviewed above. Ones that we didn’t mention yet are advanced benefits like twin-needle sewing, mirror-stitching, and the ability to edit stitches. You can adjust some stitches up to 7mm in width and 5mm in length.

There are one hundred twenty built-in stitches. Those include the entire Alphabet so you can make labels or monogram. And there are also seven one-step buttonholes, too.

When you’re ready to begin sewing, several functions make using the 4120QDC-B straightforward and nearly effortless. For example, you can wind bobbins but never worry that you’ll overwind them because of the auto declutch system. And the one-handed needle threader takes the thread and sets it into place without the need to squint.

While you sew, you can stop and start the machine at the touch of a button, as well as send it into reverse. There is also a speed control slider that takes away the need to use the foot controller.

Finally, the seven-piece feed dog system keeps the fabric flowing smoothly under the needle even if there are layers. And you can raise the presser foot extra high to accommodate thick quilts.

More features of the Janome 4120-QDC-B quilting and sewing machine:

  • Covered by a 25-year warranty on mechanical parts, 2-years on electrical parts, and 1-year free labor
  • Comes with instructional DVD and stitch chart


If you’re enthusiastic about sewing and your budget allows, the Janome 4120QDC-B is the best choice out of these three sewing machines. It comes with the most accessories and the best selection of user-friendly features and built-in stitches. It’s not a machine that you will outgrow anytime soon.

If you’re less into quilting and more into sewing crafts and clothes, you may save money by choosing the base model 4120QDC without the bonus quilting kit.

And if you don’t see a need for so many stitches or accessories, you may prefer the Janome 2030QDC-B that also comes with a bonus quilting kit.
