This air brush does me just fine. If you have never done it before like me it is good to have a try with modest gear first, just incase you don't enjoy it.
My compressor is similar to this one and does me just fine. So you could be painting for under £100 oh and don't forget to order an air line for your brush or you'll be stuck for a couple of days like i was.
Like this nice, soft and flexable. Be sure to check the fitting thread and fitting size on the compressor and the airbrush.
