I haven't heard much 'great' about the IR compressors. Some say downright garbage.
My two-stage 5hp 80-gallon Quincy cycles pretty frequently while sandblasting. As Nas says, it is a CFM hog. The other thing is having dry air for sandblasting. I run a refrigerated air dryer and metal hard lines (not just airhose) to condense as much water out as possible before the sandblaster.

If it's an oil-less type compressor, they are very noisy when compared to a belt driven type.For "quiet", if I go electric, it will be mounted in my basement. My Craftsman almost requires ear plugs.
You might want to look into a used large trailer mounted compressor. When I had a boat trailer sand blasted, that's what the guy had running a siphon feed pot. You want a lot of CFM when sand/media blasting large stuff.The reason I am considering a gas powered compressor mounted on a trailer is so I don't have to blast near the house or shop. But also somewhat to not run it off electric; PGE does a wonderful job screwing us up here in the Sierra. VERY quick to jump tiers.

Well, that's unfortunate. Seems that most manufactures now design with built in obsolescence.Everything I've seen lately says that IR isn't making them like they did twenty years ago - or even ten.
I would almost consider trying to find a PTO powered one also
