I've got one of these:
I got it used for not much money. I had to replace the catches and buy a new skewer (which was missing).
Its pretty good all things considered. The Bob looks more robust but as I use mine so infrequently I like to fold it flat.
Never had any problems with the skewer. But then I've only ever really used it for 1-3 miles at a time (I used to do the supermarket shopping on it).
