I have an Iwata CS and I love it ! works good for fine detail or painting backing colors .

Does that airbrush have seals that can take solvent based paints ?

Do you already own an air compressor ? If you do you can use it instead of buying one .

That setup looks pretty good but he doesnt go into detail about the brush really , its a gravity feed dual action , has a .35mm needle so it will spray pretty fine .(looks alot like an Iwata CR)

IDK .... I paid 64 dollars for my Iwata (no compressor obviously) and it has teflon seals so I can use any paint in it .

Dont know if they ship to Australia but here is where I got mine .......
