Yes, you can find 'sleepers' where family members sell someone's belongings and don't know values or current trends. However, the going price is $350 and up. One in mint condition can command $500. I have one that belonged to my MIL (she hated it because she liked a machine with 'substance'). I have had people offer me $500 for it when I have taken it to class or retreat because it is in perfect condition, carrying case and all. Yes, there are quite a few around but condition varies. There used to be a guy in Anaheim, Calif. that bought them and painted them in all sorts or colors. They were beautiful but not original. They commanded big prices.
