Personally, I wouldn't go near that. Before I did, I'd do web searches and see if I can find some reviews.
You might be able to pick up a used machine at some garage sale or thrift shop.
You could go to one of the sewing newsgroups, like alt.sewing, and state your needs. Sometimes the answer you get will be "get the one that works for you", but someone might be able to at least steer you away from the bad ones.
Go to a Wal-Mart, or Hancocks, or whatever, and write down the models they have. Then go home and do a web search, looking for something like "Singer XXX review", and you might get something. You'll also get a bunch of links back where the review pertains to the seller rather than the machine, but you'll just have to sort through that.
