John,

For starters compressors are a lot like computer memory, disk size, and money;
you never have enough.

That said, I run a blast cabinet and a pressure blaster (not at the same time)
with my craftsman 30 gal, 5 hp 110psi compressor.  I can blow more air than my
compressor can make, so every 5 to 15 minuites I have to take a break and let
the compressor catch up.

But one thing no one has mentioned, is the size of the nozzle.  For a 
hobbiest,
use the smallest (dia.) you can get.  Then as it wears, and opens, 
you will use
more and more air.  You blasting will get slower and slower.

John
