Don't hesitate on the Iwata LPH 400. I made the painful steps up to that gun and though it cost me a lot more then I wanted to pay, it sure is a lot better then anything else I have ever used. It sprays at 16 psig rather then the 23 - 25 everthing else uses, has a very low air volume usage at 9.5, so even a fairly small air compressor will work. I do use a Devillbiss Finishline 3 or Sharpe 400 for primers rather then the Iwata (I just can't bring myself to "abusing" a $500 gun with heavy stuff )
