I payed $80 for a 201 (K-3), it needed lots of cleaning, oiling and a few spare parts; spool pin, motor belt,... 80$ for a clean 15-91 in working condition is a good offer. Bargain machines often need a bit of work, easily a few hours, and waiting for parts in the mail. I have never regretted spending a bit of time and money on the 201 I bought, it has become my favorite machine. Fancy cabinets can add to the price.
