I asked about a pin vise at the LHS, they wanted $20.00.
I boogied over to Harbor Freight and poked around, I picked out one that had about 6 bits, AND a giant set of tiny bits in a blister pack, i think it was under $5.00 out the door.
I don't even know if there IS a brand name on it, but I know it works.
I just looked on line and don't see it, but it is in with the drill bits.
