Kobalt does make a nice little kit, none of their stuff is made in the USA I believe.
Are you looking for just the bits, or in the form of a screwdriver? I know snap on has both. I have the super small bits. Surprisingly they weren't horribly over priced. I got them for rc car stuff. Work well and when I bend/break one I get it replaced on Fridays when the truck stops by work.
I use the hell out of my Pittsburg set from Harbor.
Got a small kit from the Mac guy, was in the ad for $199. Came with a ton of different bits, hell the smallest torx is so small I can't tell its a torx without sticking it in my face.
And I bet it looks like it too
And so does ATS.
It does help that Ariel pays for half my tools.
Whatever makes you happy!
