Yeah, tuffy's rule. Sure, they are a little steep, but how much will you pay to fix what the jerk did stealing your cheap stereo? I've had mine for years now, and it's never given me a problem. Out of sight, out of mind. Installation is easy. I've never had a problem with overheating the stereo. I've got a kenwood in it, and it cranks nice, even with the top off. The tuffy is fairly waterproof too, for those times you get caught in a rainstorm. Plus, it's got a lot of room for tapes, CDs, camera, the winch remote control, a small radio and your wallet and stuff for when you're at the beach, etc. Plus, you don't need to spend the extra $ on a detachable face stereo. I think most are now, though, my kenwood's not, but it's a good 4 years old now or so.
I've been ripped off before, in other vehicles in my younger days, and it sukks bad, so I know how you feel too. Now I've got a good simple motion alarm, with an ignition cutout, and a tuffy. I've never had a problem.
Good luck
Pete
