Surge protectors are insurance. The $100 ones are the equivalent of having liability only, the $400 is full coverage. Take your pick. For what I have invested in my MH, it will not roll without full coverage nor will it plug in without full surge protection. I'll scrimp elsewhere if money is an issue. That being said, I have a Surge Guard but will buy a Progressive if this one ever gives up the ghost.
