I have got and get most of my airbrushes from Ebay. And as anyone who does this knows, people seem to be full of crap when they are describing what they are selling. Sometimes I can spot the problems. Others, like how clean they are, I just assume they filled it up with cement and let it sit for a couple years and I'm gonna have to clean it up. So I'm curious what you guys would do in this situation. I picked up a "used couple of times" NEO N4500. I wanted to review one because they do have some attributes that make me think they are actually a diamond in the rough. Anyways, it showed up and looked physically fine, No paint buildup, needle moved. While disassembling it I went to qtip swab the nozzle and I could feel it dragging. So I grabbed my Iwata magnifier and sure enough, it was damaged. I messaged the buyer nicely, explaining how everything was good, but the nozzle and asked if he might split the purchase price of a new one. It was a no go, he had no idea the nozzle was damaged. Uh huh. It sprays like crap dude. My question would be, do you (1) say Ok and move on ,(2) Hammer him with a negative (3) Give him a neutral Used does not mean un-usable. An airbrush with a damaged nozzle is like an engine with a broken crankshaft. @DaveG I know you've bought ALOT of airbrushes from Ebay, what is your expectations from the seller and knowing what they are selling?
