I've had a few of Integy's drivers from when they first got into business (early 90's). I couldn't afford a whole set back then. I suffered with "L" wrenches and then "el cheapo" soft hex drivers for the longest of times. I loved the Integy drivers I had so much, I broke down and got me a complete set :
Integy Hex Wrench Set, Ti-Nitride (6), INTC22301 I wish I would have done that in the very beginning

.
That set, that I linked, is a bit cheaper than what I paid for them. They have helped me put together many kits and maintain them through the years with no complaints here. I still use my Integy .05", 1/16", and 2.5mm hex drivers from the 90's and haven't had a problem with them yet.
