I'm using a refurbed Brother CE-4000 that I bought through Amazon at about half price (90 bucks). I have barely scratched the surface of its power. Save for one experiment with making a buttonholr on some scrap, I haven't tried any of the other feet that came with it. It's got a couple of good stiches I'm using for logo embroidery, and great ones for hemming. Easy to load and simple to use. Quite pleased with it.
Odds are most of the problems I'm having (keeping the fabric folding over for hems, etc) can be solved by those feet. I'll have to look into it.
