I would love to have a heavy duty shop stand like the Park 302, but I don't have a spot I can dedicate to a more or less stationary stand. Plus, most of the time I prefer to work on my bike outside. I have a Park PCS-1 to which I have added the recently available adjustable extension. I have found it more than adequate for my needs. The $20 wheel truing add on does a great job for me as well.

I am surprised at the comment about the Minoura W-300 and narrow tubes. When I was looking for a stand I had the opposite problem, finding a stand that would handle oversized tubes. The PCS-1 clamp will handle about anything.

FWIW, it is recommended that you clamp by the seatpost which is more robust than the bike tubing and less likely to be damaged. I don't always fool with extending my seatpost enough to get the clamp on, but then most of my bikes are old steel frames.
