I have one of the Feedback Sports stands and am very satisfied with it. They do fold up quite compactly. As with the Park's, they aren't cheap but are a life-time investment and you can't go wrong with either.

BTW, if you have a carbon or thinwall aluminum frame, always clamp them by the seatpost. I bought a couple of very cheap seatposts of the right diameters and dedicated them to the repair stand but I only have two diameters (27.2 and 31.6mm on my bikes. Park makes a universal size work-stand seatpost replacement for those who work on a wide variety of frames.
