I'm shopping for a new air compressor. I think a 60 gallon 10-14 scfm should meet my needs but I'm not sure and don't want to have to buy another later on.

The compressor will be used to air up truck tires, run a a needle scaler (10 scfm) and I will probably purchase a soda/sand blaster and spray painting equipment. I don't want one that has to run all of the time to keep up with the scaler. I think that is my biggest load.

Also any input on screw type vs 2 stage. I was told the 2 stage is quieter than a screw type. Which is more efficient?
