Which Air Compressor should I buy?

I have an 80 Gallon 2 Stage Ir one. Don't remember the cfm but it is up there aways. Got it as a refurbished one from Home Depot for $700 or so. Had one of those little 30 gallon deals. Was using my plasma cutter with it removing the rivets from the body mounts of a Ranger I was working on, it had ran a good 30 minutes or so without shutting off. I heard this banging sound in the garage and lost pressure. Went in the garage and the pumps innards were now its outards.....Sprayed oil all over the ceiling floors and walls.....
