I purchase the 3stage Fuji. I am very pleased with it's performance. I have sprayed latex thinned with flotrol, oil based thinned with paint thinner, which I am painting a cedar square picket fence. It's great getting in behind the rails & gate X bracing. I have sprayed water based General Finish with good results. I do need more practice, but well worth the investment. I did purchase additional tips, #3 & #5. Good luck. Don
