Wow! Pawn shops that don't deal with bicycles? That really does suck!
The pawn shop down the hill from me always has 5 or more outside for sale.
The problem is he is too greedy. I saw a Schwinn Landmark there about a month ago.
He wanted $200 for it. WalMart sold it brand new for $159.
Keep checking estate sales and garage sales. There's a good one waiting for you to own it.
Here's a half decent China bike from WalMart.com
