Trumpy... I'm a little surprised that you have never used a multi-bit screwdriver. It seems that pretty much every person I work with has a Klein 10-in-1 now, and I figured that it was pretty much the norm now. Personally, I love 'em. The nut drivers are great, especially when installing lots of fluorescent light fixtures with the phillips head ground screw that also will accept a 1/4" (I think?) nut driver. All I have to do is pull out my robertson bit and I have the proper size nut driver.
My favourite multi-bit is an Ideal unit that has a wirenut driver indented into the handle end. I twist and trim all my splices, then insert my screwdriver shaft-first into my drill, set the clutch to 4, insert a wirenut, place it onto the splice, and pull the trigger. Presto! the wirenut's on. It saves my wrist from twisting them all on.
and that's my $0.02
Shawn.
