Family member has had a hobby of fixing up little digitals. Perfect for wall of pride & wall of shame pictures. He's going to stop for a while and has a few to peddle. Usually gets $40-50 each, some with manuals, most without. You'd have to get card & reader for them. We've had good luck with them.
If anyone is interested, e-mail me (see profile) and I'll put you in touch with him.
