Unless you have a specific reason for a 1000W generator, I would go with a 2000W. I have a 1000W Honda and when I went to use a small air compressor the 1000W would not run it. I got a 2000W from Costco, does a good job and is not much bigger or heavier than the 1000W. Honda, Yamaha and Subaru all make great generators. I don't know how long the Costco generator would last as compared to the name brand generators as the price is much lower.
