I have one of those too but it is single stage. It pretty much runs constantly when I am sandblasting or orbital sanding, but it does everything else with no problem and not much running. Paid about $350 at Tractor Supply.X2 The oil free compressors are just too damn loud to work near and I have to believe the oil improves the lifespan of the compressor. I have had a CH 60gal vertical for near 10 years and it is still going strong. My next compressor will be a 80 gallon. I think the bigger tank allows the compressor to do less work and it would drive me crazy waiting for anything smaller than a 60 gal to keep up while working.
Looks like you did pretty good there, Moj.
