Suggestions on cheap humidor options?

If I recall correctly, I paid $7 or $8 for one of my hygrometers. Got it at Wal Mart, in the same area where you would buy outdoor thermometers and barometers. It's roughly a little smaller than a deck of cards.

I bet if you put up a WTB post, someone around here has a 25 stick humi they'd sell.
