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

I have the Fugi Q4, would would never conceder anything less than a 4 stage. My next choice would be the Apollo but nothing smaller than their 1025.

For latex paint an HVLP system is not the best answer, with a pressure pot they are not to bad but still not the best way to go. If you do get a pressure pot get a 2 gallon minimum, that way you can just insert a 1 gallon can in it. You do not have to clean the pot as the paint stays in the original vessel.

I have all of the Fugi tips and you still need Floetrol to get it to layout properly.

I much prefer a pressurized gravity gun, easier to clean.

For latex an air assisted airless pump (very costly currently) or a conventional airless is your best bet. If you only need to spray latex once in a while you may want to conceder renting or buying a small airless.  

The gun is the most important part of the system, the better the tips and gun the better the finish.    

Here is a pretty extensive thread from JLC on the subject of sprayers;

The new Fine Homebuilding has an article about exterior painting.  Compares sprayers and doing it by hand.  I just got in the mail about 2 hours ago, so I haven't read it.  If you plan to paint exterior stuff like a fence and deck, I would not go with an HVLP.  I have the Fuji Q3 for furniture and I absolutely love it.  I've done everything from shellac to milk paint (General brand thinned by about 10%).  I'll post an update when I read the FHB article.

If you decide to go with Fuji gravity new style gun and 3M PPS, the right angle adapter is #24.
I purchased my gun from Roger Phelps (highly recommended) but he does not sell PPS system. Purchased mine from TCP Global. #24 adapter was about $20. You will need a pressure cup and liners. I went with mini pressure cup. If you need part numbers I can most likely find my invoice and advise.

+1 on Phelps Refinishing.  Great service.  Love my Q4.  Highly recommend the gravity gun as well.  The regular 1 quart gun gets in the way a lot.
