I'm thinking about getting one of those, or a wall mount. I have a floor stand now - there are two issues I have with it. Well, three really, but the third isn't a fault of the stand.
1) the clamp that holds the head assembly onto the post (same as it is on the one pictured) is plastic and clamped by a pair of small allen-head through bolts. I can't draw it up tight enough to keep it from pivoting when there's a bike on it. Usually isn't a big deal, but sometime annoying. I think that Park's pro-level stands have a shaped tube, so the head is keyed to it and can't pivot.
2) it's sometimes tough to keep the floor stand from rocking if I'm working something loose or doing something that involves a lot of back-and-forth movement. Case in point - I had a Kona frame on the stand last night that belongs to a friend. I was putting a coat of wax on it after cleaning it, and I had to put a foot on one of the stand legs to keep it planted while wax-on, wax-off. A bench or wall mounted stand would be inherently more stable.
The third issue I have isn't a direct fault of the stand itself. Rather, I'm finding that one stand isn't enough. Inevitably, I've got it tied up with a project bike, when I have to perform some service on another. I either put the project aside or service the other bike on the floor. So, I think I can justify a fixed-mount stand as well as the folding floor stand...
