GameGear score at Goodwill

I generally avoid Thiftstore and GoodWill in particular because it's almost always so much junk, but one of the nice parts about living in remote Montana is most people don't like dealing with ebay, understand craigslist(it's huge in louisville), or know what stuff is worth. Because of that Goodwill and Pawnshops are goodmines for videogame enthusiasts. This week I found a Dreamcast Concept 4 race wheel in the box for $2 and this big set of Gamegear stuff for maybe $20. Pics below. I know this stuff isn't for everybody but I'm pretty bad videogame nostalgic.
