update: I don’t think the M343D is an old model anymore. I came across a Brother social media post in 2020 (that I can’t seem to refind) that said it was new? I’ll need to look into this more closely.

Their features are similar to the budget 2104D which is still being manufactured and gets more accessories.The 2104Dis a good choice for sewers who just want the main 3 or 4 thread stitches, easy threading, and don’t want to spend too much. Good price The unit has a built-in rolled hem feature, an electronic foot control, and comes pre-threaded. The upper knife can be easily retracted for more creative projects. One of the main positives of the 4234D is its ability to work on pretty much any fabric weight/type and deliver perfectly hemmed seams or decorative effects every time.

One salesperson said it’s a “good, solid, quite robust option”. Important for regular sewers who want a more durable machine. Easy to thread If you're sewing with both needles you use a dotted line if you just sewn with the right needle you use the bold line. That is such a useful little bit of marking on Janome. The Juki MO-654DE works with 2, 3 and 4 threads and features built-in rolled hemming. The built-in seam guide allows you to create the most possible accurate seam allowances. The M343D comes with a LED light and it has to be said, it is very bright. Strangely enough it is a lot brighter than the one on the Brother 1034D and I can’t quite fathom out why? Accessories There is a thread tension dial for each needle thread the lower looper thread and the upper looper thread. Retractable Knife BladeHowever, if that’s not an issue, don’t let that one problem put you off investing in this otherwise great machine. You can easily adjust the length and width of each stitch you create by simply turning the dial to the size you want and as well as standard stitches you can also use it to create more decorative stitches and finishes. Chain-off stitches for instance. An adjustable differential feed. Machines with this feature have two feed dogs beneath the fabric working independently. You can adjust them depending on what you want to achieve. It comes with an adjustable stitch length of 1 mm to 5 mm and a cutting width of 3 mm to 7 mm. In terms of speed this is a fast machine with the ability to stitch 1300 stitches per minute. The M343D can easily convert to a free arm for sewing cuffs and sleeves and comes with lots of useful accessories, including tweezers, a needle set, foot control, and thread nets. It features dial controls for stitch width, length, and differential feed.

Sewing Machine with 2 Power Supply Modes: 4 * AA batteries (not included) or AC/DC electric power adapter (include). Always make sure the power switch is on the "OFF" position for safety. A free arm for sewing collars, cuffs, and sleeves. This tool allows you to easily work on small areas and is especially helpful for those who deal with children’s clothing. The differential feed provides precision stitching and has a ratio of 0.5mm to 2.2mm.The cutting width is adjustable from 2.0 to 5.7 mm. With a built-in rolled hem it guarantees the highest quality finish every time.There is also a reference panel on the machine, which helps with selecting the correct tension setting for various stitches. This is a handy feature as it saves the need of having to serge-test seams on an old piece of fabric. Both only come with the standard foot and no waste tray. My 3 Best Buys all came with more accessories. Other positives include a 4mm stitch length the rolled hem conversion and the differential feed. The differential feed on this model is ideal for more demanding fabric and has other applications such as for gathering.
