I m thinking DeVilBiss STARTINGLINE HVLP Spray Gun for Painting Control 1.3mm Gravity Feed Paint Gun with 600milliliter Plastic Cup from Amazon for $89.99
what do you think?
Side note, i also do large format photo printing, which i sometimes cover with spray on varnish, so the gun may end-up getting used for that too… need a good quality mist, no large drops…
