I inherited my clubs from my brother-in-law. He gave me his King Cobra driver, and I even managed to get than "ping!" out of it. I still have a slice going, so I'm gonna invest in a couple of lessons.
If I start getting better, I might try buying a used set. My brother in law got himself a pretty good set of year old, barely used Titleist's for about $300, so if I start investing more in some clubs, I'll do that.
