Ditto, Honda...
But, our whole house propane fueled Generac has run well for almost 9 years;
a friend down the mtn has a Generac "portable", I forget the model # and rating,
but it was considerably less than a comparable Honda.
Not pushing Gen, but here's a link:

I agree w/JCL: you will be addicted to wanting to turn "more things"
on, though if your need is very, very occasional, or if it is a disaster
only back up, you might just cop the watts you need via most sites'
load need tables. The other problem is having enough fresh gas on
hand to run the sumbitch...gas at the corner station is hard to come
by when the crap hits the fan.
Up here, ours is a necessity for keeping the juice going...
