I don't own a Tokyo but from what I have read in some of the reviews, the folks at Citizen actually tune the bikes they sell before shipping them out to their customers. That means that the shifter and the brakes are adjusted properly, and the bearings roll freely so that there is no binding. If that means anything to you, then it is a bike you should consider, and it is within your price range.

I actually own a 16" folder that is similar to the Tokyo called the Swift. See avatar. Not to be confused with the Xootr Swift. I think the Tokyo is superior to my bike.
