That 2000 is a great size for portable. I would love one but have the 3000iS for temp home power but it is heavy to haul. I can put it in the back of my pickup but I don't move it from there when going on the road. Unfortunately hard to justify another just because it is lighter.
Always tradeoffs..... A friend of mine has the same iS - easy enough with 2 people, but not anything you'd want to back pack anywhere.....
Their new 3k iK is quite a bit lighter, but you have to give up electric start, and some sound insulation. For my uses, I'd prefer your iS, but if I was moving it around a lot, that iK would start to look good.....
