Ola,
sorry, been racin , not playin on the comp,, double grinzzzz*.....
I just noticed you're looking for a good airbrush,, I'd recommend choosing among the gravity feed Iwata line-up... something like an HP-CS or I think the revolution series there is a similiar model with a .5 needle in it to allow for that "learning" curve... in all actuality the revolution soinds like it would fit you perfectly,, then maybe progress into the HP-CS model....
I've used badger's, pasche's a couple of other brands, and finally tried an iwats,, and I'd have to say (and this is just me) but I won't use any other brand again....
with the fine line detail you'd want to be able to eventually get, badger won't cut it (1mm 'll never happen with a badger unless you thin the bejeebish out of your paint, which gets to be a hassle),
pashe's dont hold up well under laquer/water changes, then massive cleaning over time, but do have amazing detail capabilities.
other brands dont come close to the reliability or detail work you can get out of either one of those above brands... but the iwata brush I have now (i started with a revolution can't remember which , just that it was a gravity feed w/ a .5mm tip, for a couple weeks, then switched to an HP-CS) shows tru-colors in reliability, fine fine detail work, and durability.., all these things add up over time and allow you to either get very creative with your work with no limitations, or if your brush doesn't' have all these things, it will limit your creativity when looking at a new "piece", or lexan-body..
I looked through the link someone posted about beginning tips and airbrushing, and it looked like pertinent information that you could use, but I'd add in if you did go with an iwata top feed, you could spray laqs or water paint at about 35-40 psi at all times and not really worry what media you were using or the thickness of the paint, just focus on your work...
umm dont know if this gives any usable info,, maybe just another opinion,,, hope its something that helps...
Lates!!
