I know the ET800 clones are seductive because they cost about a C-note. However, there are plenty of YouTube videos showing how spiky/dirty their power is.
They have a place -- if one cannot afford better, you have to do what you can, no shame in that. They are also OK as true emergency generators, assuming they can power a sump pump or other items.
However, if I had to buy a generator on price, I would go with the above mentioned Champion. I would guess it comes off the same Chinese factory lines as the no-name brands, but CPE has a very good reputation for supporting their products with parts and tech support.
No, it isn't a red/blue, but it is something that you won't have to buy ten of. The local Tractor Supply has them at $329.99, so for the price of a couple of the cheapies, one can have something that will last a long time.
