Anyone have one, installed one, paid to have one installed?? After having to replace the brain in my hot tub for the 2nd time, the guy I found to repair the circuit board this time recommended I look into getting one in case it is power surges frying out my boards. We do loose power from time to time each year with heavy storms. Anyone have one installed they'd recommend? Any insight on self-installation or idea of how much an electrician would charge?? I've watched a few videos, and although I'm pretty handy, not sure I am up to working inside the breaker box.
