I have a Honda eu3000is, and I'm extremely happy with it. I think it's the most quiet genny in Honda's lineup actually (quieter than the 1000 and 2000 due to the enclosure design), and on Eco Throttle with low to moderate load, you can have a conversation standing right next to it.
I went with the 3000 to run my 13.5k BTU A/C, which it does perfectly. You can also go for a pair of 2000's wired in parallel to do the same.
EDIT: Forgot to mention how clean the AC power is. I also run a stack of computer and audio equipment, and there is no buzz whatsoever, and the voltage stays perfectly steady. The power is actually cleaner than that at most RV parks, in my experience.
