Rod, the 2 stage unit will be almost twice as efficient as a 2 cylinder single stage. Meaning that it will fill your needs in approximately 1/2 the time that the smaller unit will. The dual-stage forces air in to the tank on both the intake AND the exhaust stroke, whereas the single stage will only do so on the compression stroke. Keep in mind that a sand blaster uses ALOT of air volume, so don't cut any corners with your air compressor build (or purchase) if you are planning on using it for that.
