Would something like this work for model air brushes?

http://www.bunnings.co.nz/ozito-12v-dc-digital-mini-compressor-_p00278672

It's not something I know anything about....and for the amount of air brushing I am likely to do, can't really justify a "proper" compressor.

As far as I know air compressor used for air brushing have special air container, which makes pressure changes very even and slow. It's like low-pass filter for air pressure.

These car pumps just "shots" air frequently which will just spit paint through your airbrush.
But that's IMHO, I'm not professional.

However, you can use it to inflate car tire, then connect your paintbrush to this tire and use while it has pressure inside :)

No. You need capacity and filtration.

Lazy is such an ugly word, I prefer to call it selective participation

If you are painting in short bursts then you could get one of those to fill a tank and then put a regulator on the tank and use that, but that would all cost more than a most basic compressor from supercheap with a regulator on it already.

edit: and dont get the small stanley that can hang on the wall. its output is useless. Might be ok for a tiny airbrush if you dont use it a great deal? But you will quickly curse buying it the first time you want to fill a tire up and it cant pump up the tank fast enough.

There were some interesting ones on TradeMe when I last looked for a cheapie air brush for very occasional model air-brush work.

Here's one for a hundy:

Don't get any of that 12v stuff... get a proper compressor that will handle an airbrush. A mate that's also an airbrush artist has one like this (he won awards at summernats)... http://www.supercheapauto.co.nz/online-store/products/Blackridge-Air-Compressor-Direct-Drive-1-0HP-40LPM.aspx?pid=296171#Recommendations
No good for a spray gun but great for an airbrush (I'm a spray painter these days and by trade)

There are cheap airbrushes with low power compressors on them. When I was talking with a makeup person about airbrushes when I was looking at getting one to paint models with, they said the ones with no tank have probems with a surge when you first press on the air because of the pressure build up and can take some time to get the flow right, so you absoultly have to use a double action one, which is where the paint (or makeup stuff whatever it is) is controled by one axis of the button, and the flow of air by pressing down on it. Much harder to use consistantly than a single action one where you pre-set stuff with knobs and basically hit the button to get air and paint squirting.
