Buy a real compressor, not some toy - those things will last 1-2 yrs. at most.
A real compressor will return your investment many times over.
Sears (Craftsman), Ingersoll-Rand, Campbell-Hausfield, Chgo. Pneumatic, Coleman, etc. are useful tools for much more than just tire inflation... think pneumatic tools (add a water trap), painting, media blasting, power washing, car drying, etc.
I have a Sears (craftsman) 5 HP 17 gal. upright (small footprint), oil-less compressor which I got on sale for $150. It included the water trap, 25' of 150 PSI hose, a 3/8" Air Hammer, 3/8" Air Ratchet Wrench, HP Paint Gun, and accessory kit (Blow nozzle, Air Chuck, needle chuck, and other stuff).
