I'm really surprised that people still use pawn shops to get money. They are only going to give you about 30-40% of what THEY think the value is.
On the show, it makes me laugh at the idiots who walk in with something and the guy asks, "What were you looking at getting out of this?" The seller will say something like, "I'd like to get about $2,000." Pawn guy comes back and says, "I can only give you $800." Then, the idiot seller takes the deal.

All the while, the seller could have used eBay or craigslist and probably gotten way more money.
