I've found a couple of good internet deals for <$200 on 20" wheeled folders.

Campingworld.com is selling what looks like a Dahon Boardwalk D7 (not available from Dahon distributors anymore) for $149.50 if you're a member plus $29 shipping. This seemed like a good deal to me.

Costco.com sells the Schwinn Run-A-Bout which is a six-speed 20" folder for about $180 plus shipping. Anybody have any experience with this folder? Is it a rebadged Dahon Boardwalk D6? I'm a little concerned about the hi-tensile steel and the advertised weight of 39lbs. It may also be a cheap knock off of a Dahon. Does anyone have any experience with this bike?
