My two are small. More like you'd use for camping.
The larger of the two is 1500w continuos and 2000 startup. I have it hooked to the circuit with my two deep freezers and refridgerator. I haven't tried it with the new upright deep freezer my wife recently got, but it was fine for the chest freezer and refridgerator. I half expect that if all 3 kick the compressors on at once, I probably would have to hand cycle them manually myself by unplugging one while the other two are working and then let the other run afterwards.
The smaller 1000w continuous 1400w peak generator, I have hooked to the interior lights and a few outlets in the living room and kitchen mostly.
My parents have a really nice 5500w continuous rope start which works great. But, if it's sat for a while, I tend to use a hair spray bottle with gas to prime the carb with before pulling the rope on it. Otherwise, you may be there pulling on the rope for a while.
When I worked for the catv, we had two 10k battery/key start gennies to run headends and major equipment. They were beasts, but I don't recall the brand of them right off. They were red and black paint job, but for the life of me, I don't recall the brand.
