Here is a pic of the HVLP gun from Harbor Freight, for $35 I don't see how you can go wrong for basic misc. painting esp. if you don't want to make a mess in your shop!
Oh yea, and it even came with the small regulator that is so nice to have right there at the gun. This way you can leave your compressor pumped up and then just regulate the pressure right there on the fly so to speak!
