I have a 6500w Generac. LOUD and heavy, but works well. I got it a few years back when I had a side biz repairing decorative steel fencing. Sometimes I still use it for my welder when the house current doesn't seem enough for the welder. Otherwise it just sits waiting for the 'fit to hit the shan'...

I would like to add a motorcycle muffler to it to quieten it down though!
