I picked up a general set from ACE hardware and they were very soft, so I grabbed a BM blue box for 10 bucks at a local knife shop and a 3 dollar "portable tool kit" at walgreens the kit has a driver that fits the BM torx bits, and a bunch of other useful tools (pliers, more bits, tweezers, magnifier, etc.) not great quality but for 3 bucks... The BM set has been working OK for me, it only has T6, 8 and 10, but two of each, and because they are not on one tool, with another driver, you can hold a screw on one side and tighten it on the other. I'm sure there are better sets out there, but it has worked well for me so far, and I could find it at local stores, also, everything fits into a small cigar box, Blue Box, little tool kit, lube, loctite, etc.... my little knife care kit. That said, I would like some really nice ones eventually, and would probably pay for something like a craftsmen set that is not portable, for the sizes I use the most (6 and 8 mostly for me, pocket clips and pivots

)
edit - sorry, late on the draw here, should have not written anything.. enjoy your drivers!
