Paint Gun Recommendations for a semi-pro

I recently bought the Iwata LPH400 with the Platinum 1.3 tip. Have used it for both base and clear coats and love it. You have to spray much closer to the piece being painted but the results or phenomenal. No need to cut and buff anymore.

Just FYI- the paint supply store I use is also a custom, high end body shop. All they use are the LPH400's. Only difference is that the owner has everyone of the guns set up with the Orange tip. This is designed for water based paints which we don't use much where I live. He doesn't use any water based paints but said the results using that tip is the reason he won't use anything else.
