How big a part of your camping experience do you feel the generator will be?
Moderate to heavy use I would advise staying with the most popular brands, i.e. Honda, Yamaha, they are both quality units and have very good dealer networks.
I have used both and have been very pleased with the performance.
Re-sale is excellent for both brands.
Infrequent, light use may warrant consideration of the cheaper offerings.

So when is this..."old enough to know better" supposed to kick in?
