I am considering buying a bench mounted repair stand for a bench project I am going to work on this summer, and am curious about opinions on the Park Tools stands. In particular I'm looking at the consumer PCS-12 and the professional PRS-7 and PRS-4, although I've more or less effectively ruled out the PRS-4 based on price. If the PRS-4 has a killer feature that would make it a good buy over the other two, let me know - I didn't see much that would merit the extra money.
So basically I'm looking at the PCS-12 (80-90 dollars online) and the PRS-7(about 130 online). Does the PRS-7 have a rotating clamp? Both the PCS-12 and PRS-4 explicitly state that they do, but the PRS-7 looks like it does as well. If not, then this seems to be a no-brainer - PCS-12 seems like a good buy. The PRS-4/7 looks to have a much nicer clamping mechanism, and probably more robust, but I suspect the PCS-12 would do just fine as well.
Anyway, has anybody used these stands and how do they compare?
