Lineslinger I have had 2 Msd boxes go bad. First was from a welding bracket on the car. I didn't unhook the power and it blew the box. 2nd was the ground wire connection was weak, and cooked the box. Both where repaired from MSD with no problem and no charge, on shipping. Since I have learned these lessons no problem. I do carry a spare with me. My whole ignition system is MSD. I mounted my box under my glove box, next to my ECU. They are kept clean and dry. The air flow that comes from the front of the car for the foot box blows on both modules. No other problem at this time, but a do carry spare box, crank sensor, and distributor module, Coil I can get local at any speed shop or Auto-Zone. Rick Lake ps carry basic tools to change this also.
