Preval paint sprayer, anybody tried one?

I'm considering doing a low budget, somewhat temporary paint job on my Dart, just to get it all one color again. I'm going to seriously consider using this system: http://www.tcpglobal.com/Search.html?query=Prevel#/?_=1&q=preval&page=1

Have you seen the results from one of these? I can't seem to find much info on them; how many power unit refills would it take to do an entire car? I want to try a satin paint, something in the blue tint.

I have painted before, I did two different cars and they turned out nice. I used traditional equipment on them though. Back when Imron was a popular single stage paint.

Opinions? Any experience with this? Could it give better results than an aerosol paint job? TCP Global,has treated me well. What's your budget,and expectations?....

Thanks

They are great,for small projects (dash panel,door hinges,e.t.c.). The pressure charge cans,freeze quickly on bigger jobs. Those refills cost like 4-5 dollars a whack.Personal experience, here.
