If I had a choice between Propane and gasoline generator, I'd pick propane. Cleaner burning, and the fuel doesn't go bad. Buy the propane tank, don't rent.
Do you mean propane generator or inverter?
I think the one I saw at Menards was an Inverter. Price was $695.00 if I remember right. 1000 watts.
Definitely know about the rent vs. buy the tank thing with propane. I rented a tank once for our gas fireplace. We didn't buy enough gas from the gas company so they came and got the tank gas and all. At first the guy said, "You have some gas left we'll pay you for the gas." Then it was, "I was mistaken there was no gas left." Uh huh. I told him in a polite but terse way, "Your company will never get my business and nor my father's. My father had them come and get his and he bought a tank. He doesn't buy propane from that company either.
