I don't know enough about all the varieties of machines to answer your question, don't know what it would cost new but if it works and buying accessories is less than a new one that would be a good deal. In general I guess that is the gamble. Sometime you get a great deal and sometimes you get a dud. I try to remember to ask myself -can I afford to lose this money if it doesn't turn out to be what was expected. If I can afford the risk, I take it, if I can't I pass.
