I haven't used that regulator but I have an ultra-cheapo regulator that came with a keg kit and it works great. I can't imagine you'd have any trouble with that one- just treat it nice and it should work great.
I can't be arsed to keep up this list of what's in the fermenters, but hey, check out the cool brewery I own!
Yes, I've purchased the Kegco 542 regulator and it works great!!!! I ordered it from Beverage Factory since our old regulator died and not only is the regulator great but the staff there were friendly and helpful too!
