I'm with you on the black Xcelites. They're good, unless you're dealing with shitty screws, which they cam out of.
There's no way in hell any vacuum cleaner is going to be made with JIS or Pozidrive screws. Cheap, soft, poorly formed screws? You bet.
I have a feeling that the stainless steel screwdrivers from Craftsman with the blue handles are a bit harder than usual steel drivers. If I need to do something ugly like hammer a screwdriver into place, then torque it, I grab one of those and they do well, and aren't silly priced. Mine were made in the USA, but hell, they could be chinese junk now.
I've fussed with Wera "lasertip" drivers with ribbed tips that grip crappy fasteners at trade shows, and they seemed OK. Never bought a set though. Their website is unbearable to look at, so I've never located part numbers and tried a tool distributor.
Wiha phillips drivers in the #1 and #2 side seem to run real small (too narrow and too pointy), and slip out. Not impressed at all, and the #2 is useless for standard electrical type work such as installing outlets. Their precision drivers are good though.
For small JIS drivers, go Moody tools. They're made in the USA, and of acceptable quality for the most part. I used these on camera gear, which is JIS, and not phillips. You can really feel the difference. JIS drivers on JIS screws do not feel like they want to cam out.
Never been dissapointed with a real Klein driver either. They work great. The imitation stuff is horrible though.
