There is one in Iowa City, IA, great folks and decent selection of used bikes. They also sell new stuff too.

I think one glaring problem is supply of decent used bikes. Ever since WM got into the bike sales business at their current scale, the quality of used bikes has declined. Years ago I could buy Schwinns, Raleighs and even a Huffy that was of usable quality. Now the stuff that comes out of the various marts is so poor that is worth little more than scrap. I know in my area if you can find ANYTHING other than a Next or other BOS anywhere you are doing well. I did scavenge the trash piles an aluminum Next frame was worth almost $20 last year, now about $2 for scrap.
