I have a15-91 that I bought at an estate sale for $60. It is in a cabinet, perfect condition, all the attachments, booklets everything you could want. Please don't get discouraged, there are more out there like mine and it will just take some time and luck to find one. This "antique" business the guy was trying to sell you on is silly. There are those who think just because it is old it is worth something. Pass up the broken down hopeless machines as there are the nice, well kept ones to be had.
