Without a doubt this is the finest inverter I've ever owned.  Of course none of the others I've owned have been over the $150 price range.  I wanted/needed an inverter that I could trust to run for months/years if need be without a hiccup for a reasonable price.  Past units I've owned have run VERY hot and then the fans would quit and eventually the entire inverter would stop.  Sure there are more expensive units but from what I've read from past users this Tripp-Lite PV1250FC will fit the bill and last for years.
