I want a nice torx set....

Wiha. I learned the hard way. But a cheaper set and thought I had stripped the screw, but found I had stripped the tool. Wiha are nicely hardened.

If you want something easier to carry around, I highly recommend Hama torx set.

I bought this set. http://www.amazon.com/Wiha-36392-L-Wrench-Short-Piece/dp/B002QV0FGA/ref=sr_1_32?s=industrial&ie=UTF8&qid=1426677514&sr=1-32

They work a treat.
