Roadjunkie,
You need to make your own value judgement.
Champion is great for price.
My experience says that their sound level measurements are off by some, and I know that their fuel consumption is higher than the inverter units. I also have heard (not first hand experience) that parts are not easy to source and that the basic quality is typical of Chinese products.
By the rating, that unit will do a lot, but not all at once.
It is inexpensive enough that it will tell you if it fills your needs. Just be sure to do the prescribed maintenance and it will last long enough. It is unlikely your ownership will be problem free. Change the oil, and drain the gas when you aren't using it and it will be good for a long time. True, it probably won't last like an Onan or a Honda, but you can wear out a few before you would have paid for a Honda.
