For an entire package? You might check some of the deals on e-Bay...
I use a Badger 200 single action, and a Badger 360 double action, with a Paasche cmpressor with a regulator/water trap.
If this is your fist air-brush, I have some tips in my Tips section of my modeling site... look under tips/painting/air-brush... Bu tbasically I would recommend getting an inexpensive air-brush to try out, and see how you like it. A single action will do, and be easier to get used to. A lot of people start with a Badger 350 external mix, or something similar. It's inexpensive, and does a good job.
There are some good sites for shopping on-line alos... I like Dixie Arts at:
