NASA HPDE events are good. You are paired with an instructor, once he or she feels that you won't hurt anyone, or yourself, you can drive on your own. The instruction is adequate, but it is a good way to get track time cheap.
I've done two at Mid-Ohio, you really can't beat it for the quality of track you are on.
You tech your own car, all it needs is a working seatbelt, and to be in good working order. You will need a helmet. That is all.
Let me know if you have any more questions. smile.gif
