An EMS or whatever you want to call it, as said many times, is a great idea and cheap insurance.
You can either get a quality US made Progressive Industries one with a lifetime warranty or one of the off-shore models with a 1 year warranty. Based on warranty alone - easy decision....

Read the warranties carefully.

One thing I like about the PI EMS is that it shuts you down at 104 volts while the other popular one shuts down at 102 volts. 102V IMO is too low. I read in one AC manufacturer's manual recently that anything lower than 105V can cause damage and I've found that 105 is a commonly mentioned threshold where you should manually shut down if you don't have automatic protection.
You appear to say that 105V is as low as you should go. I agree. That's why I bought an auto former.
But neither PI or TRC units meet that 105V criteria.

Depends on the unit. I have a hard-wired 50A 40240 and the only protection missing from the comparable PI unit is 220V.
