i dont have a need to do tons of fancy stitching, i just want the basics. because i dont have the money to buy a super high end model though, the middle quality ones that are computerized seem like a problem waiting to happen, where theres often a computer problem.

so i greatly prefer mechanical type machines, and in general am on simple is good, or at least not bad =)
