What are you looking to power up?
You've seen my truck, I have a 1000w Tripp-Lite inverter which rarely gets used. what it's done is power the camper (with small microwave), charge cameras, and charge laptops. I've also run angle grinders, drills, skil saws, and 120v lights off it. Some days I wish I'd have gotten the 1500w one as I could run a Keurig, but then again other days I'm glad I'm outside with a stove heating water.. seems to be meeting my needs. I had one in the 80 too, and couldn't kill it.
Edit: this is what I have, Marco turned me onto these. they work awesome.
here's the 1800w- would run just about everything in your kitchen or bathroom http://www.ebay.com/itm/NEW-TRIPP-LI...item46108dc479
