i use the vl as well. i like it alot, ive had it for years. maybe one day ill upgrade to a gravity feed but the budget isnt there for it right now.
their compressor isnt for me though, not enough constant pressure.
you would be best off to use a compressor with a tank on it and a regulator and a water trap.
all shot with the vl.
another item to consider when buying an airbrush, parts interchangability/availability. alot of airbrush parts are propritary, meaning they only fit that particular model/brand. make sure you can get the parts when you need them. seals, tips & needles all wear out and if you cant get new ones you now have an expensive way to hold down the instructions for your next build.
