looking for an airbrush

Fine line brushing depends on the needle your using, thickness of the paint, distance to the object. My Iwata came with a .35mm needle, which is a common size.

Thank u both for the advise this is supremely helpfull. I've seen a few on ebay advertise as good for nail decorating I imagine these are.good for making fine line that considering im working with small action figures

I agree with Truwer: invest in a compressor, with a tank if budget allows for it. I'm also a member at another customizing site, where a lot of Transformers customizers reside. And they mostly use an airbrush for their customs. When I asked what setup I should buy, many guys pointed me in the direction of Iwata.

Iwata, Paasche, Badger, they're all airbrush makers and produce quality products. You can make it as expensive as you want. But a gravity fed, dual action brush like the Iwata Eclipse I have is a real pleasure to work with and, also pretty important, easy to maintain.

First and foremost, do not go with aerosol over a compressor. I learned this the VERY hard way. The problem with those is that the airflow is never consistent whether it be from the can getting cold or the can being near empty. If you think about it too, if you do this for many years, the price of the compressor with be way cheaper than buying cans.

As far as an airbrush, I have used a Paasche Talon gravity feed (paint cup on top of the brush) and I love it. It was a gift, so I never really looked at the price, but the parts are cheap to get and easy to find.

As far as Siphon vs Gravity feeds, I think it depends on what you are looking to spray/how much you are spraying/your preference. Siphon is nice if you are spraying a lot of area as you can mix up multiple bottles of what you want and quickly swap out. Gravity is nice because it is less to clean and tends to do finer lines.
