Having owned a 5000b RP and supernova and lph400 and pro lite and can tell you this much if you are like me you like painting fast and pretty close to the panel. You will like the 5000 more than the other guns, I would suggest getting a 1.2 as the 1.3 is too fast. It just hoses material on. That being said, unless you manage to get runs (never happened to me) the material being hosed on will be nearly flawless, regardless of technique. The biggest advantage using the SATA gives the painter is that the gun does the job for you. Your responsibility is making sure the paint is the right color and mixed properly, the same goes for clear, and for opening up your wallet to buy the gun in the first place. It literally does the rest of the job for you.
Keep it clean and when you clean it be mindful of the black air ring thingy (might be the fluid nozzle im not sure) which sits underneath the air cap. You can and should remove it for cleaning, but it's made of pretty lame plastic. Be very careful removing this for cleaning as it tends to get stuck if you tighten the air cap a little too much the black air thing I am talking about will be very hard to get off for cleaning. I broke one and had to replace it.
The sata is a great gun I found 17psi at the gun worked very well I tried pressures up to 25 with no problems at all. The more air you give the gun the faster you run. It produces quite a lot of overspray but whatever.
I hated my supernova it was a 1.3 I hated it I sold it and to this day remembering the way it sprayed I still hate it. I can feel the raw emotions lol. My lph400 is quickly heading that direction as well. I wish I still had my 5000, if and when I get another I will get a 1.2.
