Now your talkin...the good stuff!!!
Same one I have installed in my Lexi.
It may seem to be expensive compare to the one you were originally looking at, but when you hook up to a bad electrical outlet and it saves your electronics, or a surge during a storm, you'll be thankful you spent the money.
Also, the internal components can be replaced via Progressive Industries, instead of having to replace the entire unit. Their service is absolutly the best and there is always tech advice (very friendly too) 24/7.
