Has anyone had any success using a Guitar Hero controller on PC and if so which version and which game did it work with?
Any Xbox controller will work so long as you have one of those wireless controller adapters. There's actually a better Guitar Hero out now, and it's far less clunky than the original. It's called Clone Hero. I'd highly suggest checking it out. Inserting custom songs is so easy that it is almost funny. Oh, it's also super light weight (60MB download for the entire game, minus songs!) and runs beautifully on almost any rig as it is coded with Unity.
Thanks - so if I get a controller off ebay etc I'd need a wireless adaptor (unless it's wired!) I'll look into clone hero too!
