Does anybody have the HarborFreight 2500 Inverter Gen?

There are three brands of generators to consider: Red, blue, and yellow. In that order. I'd place Honda a notch over Yamaha because of parts/service availability, but both are quite reliable. Nothing wrong with Champion models, although they tend to be somewhat louder than the red/blue ones.

I'd avoid the no-name brands like the plague, just because a Champion isn't that more expensive, and Champions have decent voltage regulation.
