For a really tough fixed cup there certainly is no substitute for the "big tool". However, I've had good luck at home with a standard Campy fixed cup tool and the Stein clamp. You have to use common sense since the tool reqires the BB to be assembled. If you're installing a cup you need to leave some clearance for the bearings as the cup seats. Still, for most at-home projects it works well since the clamp nearly elimantes the chance of slippage. In the rare case of a too-tight-to-budge cup, I can always go to one of those rare properly-equipped and technically-competent shops. Still, if I ever see a proper fixed cup tool at a cheap price, I'll buy one. But then I'm way deep in tools, relative to my needs.
