Purchasing my first airbrush this week!

Other than oil free, any certain specs?  I’ve read single action is better than double.  Is that just preference?

Any minimum PSI required?

This was recommended to me, thinking of getting it.

Thanks 

you need a food safe one for doing cake

Also, do you get an airbrush cleaning station?

the instructions with the airbrush tell you how to clean it -- but maybe you mean an air brush station/box to avoid overspray into the room -- plus you need goggles and a simple mask for your mouth & nose -- and there could be an air filter in the back of the airbrush box too --

but I daresay yours would need to be bigger than this one:

Personally, I love my DinkyDoodle airbrush.

I just purchased my first airbrush and have yet to try it, so I am no expert.  After racking my brain for years trying to decide what type to buy, I bought one from a local cake decorator who had never taken it out of the box.  Since it was very reasonably priced, I thought I could afford to take the gamble.  One this I could mention, the one at which you are looking has the paint cup mounted underneath the airbrush.  That works fine for painting on a canvas, but when painting a cake, it could really get in the way and damage your finish.  I would suggest an airbrush with the paint cup mounted on top.
