We have a 20K Generac that easily runs the whole house (runs on natural gas) In fact it was on when I left for work this morning (we do live in Maryland after all).

I did a lot of research on all of them before deciding on the Generac. The only one that came close IMO was the Kohler as it had a greater oil capacity. But it's switching ability didn't come close to the Generac. Part of that decision also came down to the installer- most wanted you to buy from them with a markup. We bought from Northern Tools and found a local guy (Bestland Electric) to install who we trusted. They may even go to the Eastern Shore I don't know.

We've had it for three years without a problem; I change the oil and plugs twice a year, check the belts etc. At $3,500 for 15K you can't go wrong we paid just over $5k for only 5KW more. There were a lot of b*tches about all the generators when I researched- I think Generac has more only because they sell more.

Hope this helps.
