I've bought several used machines, either at thrift stores or a dealer. The last one I bought at the local Humane Society thrift store for $10.00, sews just fine, never had any problems with it. I got it serviced last year because it was getting a little loud, now it just purrs along. Definitely, I would recommend thrift stores or dealers, you'll most likely get a much better made machine for a whole lot less money.
