I purchased a few (for gifts for people starting to sew). Just be careful- read the feedback, etc. I got one machine, a pleasure, another not what it was represented- still haven't had the time to really sit and figure it out. Probably going to take it to local Singer place and ask for lessons to really use it.
Bought my brand new Juki also from Ebay- allbrands.com. Love it, was the best purchase I made on Ebay (or as my family calls it- Epay).
Good luck! And don't forget all the fabric deals out there- I have added to my stash by buying bundles and scraps, etc. Or- to find more of something you can't get anymore- there's also something fun to be found on Ebay.
