I got this one in Costa Rica for what would be a little less than 9 bucks. This would've easily gone for $30-$50 at a shop around here.

I also own one of these little guys, but I'm trying to get it back from someone else's house right now. Very tiny, but extremely well made, especially for the size. Here's the picture off the seller's site:
