Here's an option from progressive.
Hopefully its a decent one because that is the one I bought... :) 4.8/5 stars with 600+ reviews is decent though
Protector
As long as you know that one only protects against surges and only
indicates if you have an open ground, open neutral, reverse polarity or mis-wired pedestal condition. If you are going to use it, at least plug it into a pedestal by itself to check the lights for a problem before plugging the TT into it. (Note that you should not plug your TT in while the power is live, so shut the breaker off first, then back on.)
An open ground or neutral can still happen any time after you are plugged into a pedestal so don't assume you are 100 percent safe. We had an intermittent open ground at a CG once so it can happen.
Still better than nothing as mentioned somewhere above, but for the extra $150-200, I would have sprung for the top of the line PI EMS.
