I have two of the Graco units, dont remember what model but their the better ones not top of the line but up there. We have 14 rental houses with decks. In the past four years I have painted every one of the houses, inside and out, sprayed roughly 1500 feet of picket fence, and sealed the decks in my spare time. Thats just evenings and weekends. The Gracos are excellant products. I tried doing the HVLP method first and it was less than efficient too much monkeying around. With the airless you stick the tube in the five gallon bucket and go. Make sure you have at least a 100 ft of hose and match your nozzle to the paint thickness or you will put on far more than you need. I learned that the hard way. Keep them clean and use pump juice while stored and theyll serve you a good long time.
