My Dad got me a set of these bits at Sears. Has all the security bits in it as well as the standard bits. Check out the Craftsman 32 piece Security Screwdriver and bit set for $25.
(1) Includes Torx® tamper proof: T7, T8, T10, T15, T20, T25, T27, T30, T40 (2) Fraction hex tamper proof: 3/32, 7/64, 1/8, 9/64, 5/32, 3/16 in. (3) Metric hex tamper proof: 2, 2.5, 3, 4, 5mm (4) Spanner bits: #4, #6, #8, #10 (5) For Triwing® screws: #1, #2, #3, #4 (6) For Torqset® screws: #6, #8, #10 (7) 1/4 in. sq. dr. to 1/4 in. hex adapter I'd be amazed if it doesn't have what you need, but there are smaller sets:
(1) Start here: 6 piece bit set, Torx Security $10. (2) Craftsman 7 pc. Tamper-Proof Torx Bit Socket Set $30 (Probably not great for computer use.) (3) 5 pc. Craftsman Tamper-Proof Torx Bit Socket Set $40 (Again, probably not good for computers) And if it comes down to it, you could try drilling out the security pin and using a standard Torx bit.
