Don't say the Mean Green aren't kind to you:
Here is a link on ebay for a generator I bought for tailgaiting. Several advatages:
1) Its new. Bought directly from the distributor so it's comes with a warrenty.
2) Not heavy or bulky. the thing only weighs 40 lbs. and its only about 2'x2'.
3) Not loud. Its only 60db. I put it in front of my explorer and tailgated out of the back. Over the sound of the TV, conversation and ambient noise around us....I couldn't even hear the thing. A friend asked me if I thought my battery would be dead by the end of the day because he thought I was running off an inverter and had no idea the generator was running.
4)Fuel efficient- It has a 1 gallon tank and I ran it from 11:00am-5:30pm without a refill,
5) Plenty of power. Its rated for 1250 peak/800 sustained volts I had all the power I needed. I ran a 20' TV, a DirecTV receiver, an electic cooler/mini fridge, and a large fan to keep us cool-- Had plenty of power for all of that.
6) Economical- Check out the price $99.99. With shipping my total was
$118.98- Cheaper than a marine battery and this will be giving me power for years after that marine battery is in the landfill.

And even with a marine battery you are still going to need to buy an inverter to run a TV and receiver.
