I would like to purchase my own spray system, I am leaning towards an airless pump, but what about a turbine? I would like to stay under 400$ and it wouldn't be an everyday tool? Also, what brands are good, and which do I need to stay away from?

I am use to spraying M.L. Campbell Pre-Cat lacquer (MagnaMax) at work, but what about a different type of finish like Conversion Varnish, etc... What do you all get the best results with, while not sacrificing durability??
