I got this one in January and use it almost daily:

Amazon.com : RAD Cycle Products Pro Bicycle Adjustable Repair Stand : Bike Workstands : Sports & Outdoors

Perfect for my needs.

I don't find the need to spread the legs out as far they do in the pics.

Here's a pic of it holding up my steel Nashbar Touring bike:



You can see I've got the legs closer together there and its perfectly stable even with my racked out steel touring bikes on it.

I like the clamp because its easy to lightly tighten it for the frame material. I barely tighten it down for my carbon bike, but can crank it a little tighter on the heavier, loaded steel bikes. Fits both oversized and vintage tubing.
