weight was a factor when I was generator looking. I finally just got 2 honda 2000's.
Advantages:
1) only weight about 50lbs, easy to lift and carry
2) two are about the same cost as the quiet honda 3000
3) more VA than the honda 3000, especially with the new 2200's
4) generally only need one, in fact now that we have the micro air easy start and picked up a honda 2200 (one 2000 went to our son), the 2200 will run the AC by itself even at 6000+ft, so it's very rare that I even need to parallel. If I need battery charging I can do that after the AC is off.
Disadvantage:
1) no electric start
2) easier to grow legs than the 3000
3) a slight bit more noise than the 3000.
If I had to do it again, I'd go the same route, honda, yamaha, HF all have 2kish generators that can be paralleled.
