Picked up up one of these for $200 a few months back and have been pretty satisfied with it. The aluminum frame is very lightweight, and appears to be decent quality, but the cranks leave much to be desired. I will probably end up upgrading them when I get a chance to do some work on it. The great thing about these bikes is they fold up small enough to carry on a plane as check in baggage, so you can skip the airport cab fare on your next excursion!!!
Amazon still has these for $200, and in my experience this seller shipped very quickly.
