If I had it to do over again, I would not have bought the Singer Futura embroidery machine that I did. (SES1000, sold through HSN and very similar to the 350) It's spent more time in the shop than it's spent embroidering. :( I guess I've done three or four dozen designs with it, and the bobbin case keeps jumping out of its track and getting broken. Plus, it has a mind of its own about where the center of the hoop is, where it left off stitching in the last step and where it needs to go next and it was so annoying about refusing to stitch for threading errors that didn't exist that it just wasn't any fun at all.
Honestly, I wouldn't buy any modern Singer, (or Viking or Pfaff, for that matter) although I do love my vintage and antique machines.
Instead, I would buy the Brother embroidery-only machine that walmart.com has for about $650. It's much less troublesome, and from my experience with other Brothers that I've owned, I know they make a good product.
