I dont know much about them, except that when I was checking into them for my house, I decided I want a natural gas one (vs. gasoline). It can be set up for auto switch over when the power fails. As for gasoline, I dont want to have to worry about refilling it, having water condense in the gas tank, etc. There are many generator capacities available, depending on what you want to power and how much power you need. You can start looking at samples at amazon.com. I also heard that power quality on the generators is not as good as a normal circuit. (but I am not sure) If you get a line conditioner/regenerator such as the PS Audio power plants for your equipment, then the power coming out of the generator would be cleaned up.
You might also consider getting a whole house surge suppressor, so when the power comes back up and the voltage surges, you dont damage any items in your house. Even if the power company says this never happens after a power outage, my computer repair company fixes a lot of machines that have been damaged after power has come back online.
