Airbrush Upgrade?

[toyota00]

I currently have a paasche vl. I have been painting plastic model cars and now I have been painting designs on paper. I have been using acrylic paint. My compressor does not have a regulator, but I bought it used off ebay to see if I really wanted to airbrush and I love it. So I think I am going to get a new compressor because the one I have isn't really worth spending money on.... Anyways how do you know it is time to upgrade to a new airbrush??

What makes a airbrush better then another one? When I do upgrade, I am pretty sure I want a gravity feed iwata... What do you guys think?? I hope to paint detailed fire and skulls... maybe some scenery... Just was wondering? Thanks for any help. What paint should I be using for paper?

When I paint on the paper, my lines aren't super defined, they are fuzzy as if its a crappy image in photoshop... Just little things like that, I need to fix for myself, and my painting will be a ton better. Thanks again

Is this a nice compressor?

I build model cars alot, and so I paint them. And then I am starting to paint on paper some designs and so on...

I certainly not the one to be giving advice..but..
I bought a Craftsman (Sears) compressor; has 2 gallon tank, regulator
and pressure guage, for about $110. I added a water/moisture trap.
The unit works great, I am very pleased with it. That's my opinion...
For what it's worth.

Regulators are not expensive and very easy to install. Get one and your control with the Airbrush should improve and then you will be in love.
