I don't own one YET... But it's on my list. Thinking of the same one for my red truck. I've done quite a bit of research and from what I can tell they're the best on the market right now. Iraggi used to be reputable as well but they seem to have dropped off in quality, and subsequently dropped off the face of the earth. Ohio Generators are decent, I'm running one now. Nowhere near the idle amperage that I really need, though. Can't remember what it was exactly.
EDIT - Iraggi is still around, apparently. No idea what their quality is like nowadays though.
