Paint gun

Ok... I'm looking for a gun to shoot my epoxy primer...and to shoot finish color (Or should I get two separate guns)? I have a 5hp 80gal. tank Quincy compressor so air is not an issue. I'm looking for a decent quality HVLP type gun.
Any advice would be greatly appreciated.
(I also have an older 2 stage turbine air system from TIP...anybody use a turbine system)?
Thanks.
