Have to agree with roosterfish.
My 2nd Compressor set me back $450, my first was more like $170.
Both are good and do the job, difference is the noise level that they give off and how long I can run them.
My 1st Compressor has no tank and is NOT silent, the 2nd has the tank, auto-switch off and is silent but needs oil(pricey) refills from time to time.
Really depends on your needs and your budget.
BTW, nearly went for a compressor that cost $900, when a few guys in the shop told me that they are using my current compressor(2nd) and it fulfills our needs better than the more expensive one and has a very similar performance level.
