I don't know, but in the reviews I've read and hunted through online, a lot of upholstery type folks seem to prize this machine. There are bits and pieces you can buy for it like leather working needle sets.

This machine is still made from iron and steel construction, no plastic parts inside. The most common complaint in the reviews is that it is loud as hell. Has no computer, only a handful of stitches, and comes in any colour you want so long as you want dull army drab green. You can get a walking foot for it.

It sounds good... Which is why I wanted opinions.
