Ok folks I need a little spoon feeding of information.  I currently use an Iwata Neo Gravity Feed Airbrush and it has been really good for my 1/48 and 1/32 scale kits however now that I am looking at doing 1/72 I really need to go down to a 0.2 size needle for pre-shading and that size needle is not available for my Neo.  My question is, what would be a good brush to get?  Would probably only use it for pre-shading so I really don't want to break the bank.

Thanks
