WTB: Safe roll bar.
 

I'm looking for a decent roll bar for a 16 year old I go to church with who was given a 91 Miata by his uncle. I don't really care what it is specifically, just that it's safe so that his mother can quit thinking about him getting squished by a dump truck and let him actually drive the car.

Hard Dog, Boss Frog, Kirk, Autopower, etc would all be fine. My only concern is that it's cheap, safe and preferably within easy driving distance. I'll pay to ship a deal, though.
