Good info all around. Thanks.
I've taken Tactix off the list, and probably new Craftsman too. The Husky model looks decent, but I'm limited to what I can order on Amazon (need to use a gift voucher I have). Unfortunately, none of the other options I'm seeing there, from Gearwrench to Waterloo, get great reviews.
Re the point about weight and portability, I should clarify that I'll only be occasionally lugging this up from my basement to the garage and back down again. So while 50+ pounds will be a little annoying, it won't be a dealbreaker for the frequency I need to heft it.
