Well, I bought a sharpe finex fx2000 on ebay. was a pretty good deal i think, about half price of most of what I saw new. Said it was taken out of the box, never used. Was not able to get a tip size on it, but likely will be around a 1.4mm. I guess the good thing about those guns is that different sized tip sets are available. Bad thing is they cost almost as much as I paid for the gun to start with.
But I reckon I'll probably shoot build primer out of my old siphon cup gun anyway. Maybe by this time next year, I'll have my truck ready to try out this gun on. hahaha
