I got the Aztek in yesterday.
first impression:.... it looks cheap, lol. I guess I am just used to the all metal of the Paasches that I have. The Aztek is all plastic.
I sprayed around with it a little bit. I am really impressed with how it performs. The double action lever has ALOT of play in it. I mean, it has twice the pull back of my VL. It is really nice and lets you explore even more control with line thickness. It comes with 6 nozzles, and is a really neat idea. Each nozzle contains the needle and everything for each kind of paint. So if you want to do a .30 thickness line, you slap on the white nozzle and get down.
To clean up, you just take the nozzle off of the brush and soak it in water or thinner or whatever. You can also rinse the front end of the brush if you want, and thats it. VERY easy clean up. I think I will really like this.
