I am looking for a new (non turbine) gun for my WB finishes. Lately I have been using GF High Performance Topcoat, but I'm struggling with my existing guns. I initially started some time ago with the HF purple guns and have had reasonably good results with them, but they have their problems (difficult to clean, prone to rust, dated design, lack of spare parts). A couple of years ago I got a Fuji MPX-30 HVLP conversion gun but I have come to despise it. It's difficult to adjust and provides very inconsistent fan patterns, and I'm ready to throw it away. I have ordered a 3M Accuspray PPS setup which I'm looking forward to trying, but I'd also like another conventional gun. I would like to keep it in the $300 or so price range, and I'm looking for a gravity fed gun which could be converted to the PPS system in the future. Most of the medium to high end guns seem to be made for the automotive trade, so it's difficult to get any direct data on their performance with woodworking WB finishes.
