Why is everyone so bloody narky about this?
I'm only offering suggestions that I know work. The Amaxi is a professional solution. Anest Iwata sells the best gear in existence. The copper trap is used in a dozen good spray shops I've been to... Plus I was offering airbrushing as an example. These guys are on the tools all day and can't afford inclusions.
The pros certainly use professional dryers, but these cost an absolute bomb.
