One bit of advice I've received regarding keeping a generator running well is to use Stabil all the time, AND to start it up and let it run for a good long time on a monthly basis (I do it at the end/beginning of every month).
After being without electricity for almost a full week last summer I purchased an ETQ 7250 Watt (30 AMP) generator from the local Home Depot. It was almost surely made in China. It had the option of installing a battery to use an on-board starter. Finding a battery was a bit of a pain - the web was helpful for that. The instructions for installing it was really poor, but I took a guess based upon the provided battery harness and it worked fine. Have to say I LOVE the electric start feature. So far, so good.
BTW, the thing is a beast. Heavy. It took two beefy people to put it in my truck and to get it back out. It rolls around on large pneumatic wheels and has a large handle to pull/push, but if I have to roll it very far its work. It came with a metal coat hanger looking thing that hooks onto the frame and lets me lift it with my tractor's front end loader, but I haven't used it ... yet. Keep the weight and portability in mind when you buy.
The generator has a feature that auto-controls the engine speed based upon the electrical demand. This feature can save a ton of fuel AND can keep the noise level down. Make sure your generator has that feature.
A good friend of mine bought a generator with a Honeywell label and an engine by Honda label. It looks AMAZINGLY like my ETQ generator. Even looking at the shape of the engine block, the engine oil port, the engine mounts, the frame, etc ... The electrical outlets were different though - I like the ones on my ETQ better.
One last thought ... generators tend to be pretty loud - loud enough to anger the typical camper if running too much.
Good luck on your search!
