The most recent issue of Camping Life has a good article comparing generators in the 2000 watt range. They compare the Honda, Subaru, Coleman and a couple others. There is a handy chart following the article that compares all the features. If you see this magazine on the news stand and are in the market for a generator you may want to buy a copy. They do have a website - //www.campinglife.com with lots of camping information but not this particular article.
Here are links to two camping life articles on generations
