Can't address the generators as such. The engines are Honda clones (Honda GX 200 Series) and all the parts are interchange able as such. I put one of the 6hp horizontals on a 60's craftsmen snow blower this past fall it worked well. I will say that it didn't get a lot of use this past winter.
Somebody I know has one of the $99.00 ones and said it is fairly quite and worked well when they went camping and used it.
I have a 12.5KW Generac from 1998 and wish i bought the one that hooks to the gas line instead of gasoline. It can be a pain in the A$$. It did save the bacon with that 5 day regional power outage a couple years ago.
If you get a gasoline one make sure you have one of those jiggler siphon devices to get past the car/truck anti siphon devices. with the car and truck gas tanks just under 40 gallons. 3/6 gallon cans 2/5 gallon cans along with always keeping the tank on the unit full 8 gallon. We can run for over a week 6 am to 11:30pm
I'm thinking of getting one from Harbor Freight for my parents house. They have a sump pump, and my old one is only 1,100 watts. So its the pump and fridge and a small fan and radio and it trips on occasion.
I do change the gas out over the course of the year, fill the truck and then refill the cans. Also use stabill, de icer in the unit and gas cans to cut down on any problems.
I wired the house with a transfer switch and plug by the shop so I just plug it in, and then switch over from line to generator. Sure cuts down on the extra BS with extension cords more so in winter trying to rewire the furnace with wifey jumping up and down about freezing to death.
Also get a good heavy chain and padlock to lock it up, so it doesn't walk. The cable company has lost two chained to the pole across the street when the powers out.
It was a perfect swap the parts and bolt it down. I can say that I am a firm believer in them. Get the extra warranty and any problems swap it for another one! I'm thinking of getting another engine and mount it on another blower carcass to make a powered trailer dolly!

EDIT
I forgot to add this web site, They have a lot of great info on choosing a system etc. I do own a old generac system. I have no other interest in them. They do have the best no bull info.
It is important that what ever system you get, You figure out before hand how big you will need it. AS neither HF or any where else will take back a genny after it is purchased other than a direct swap for a working one. For obvious reasons even home despot and Lowes have certain restrictions that apply. To many people buy power washers use them once and say they are broke! :wink:
