Keilau, I wouldn't discount all shop compressors. A good one will power the airbrush and air up the vehicle tires and allow you to run an impact gun to rotate your tires faster. If I could only own one compressor in the entire house that is what I would have as I use a compressor for more than just powering my Badger's.
In addition to my Paashce DA400 compressor for airbrush, I have a Sears oil lub 1-hp compressor in the garage. Yes, the Sears comes in handy when I sprayed paint my cedar deck this summer. Good for small nail gun and topping off the tires too, but not much else. If I want to drive an impact wrench or any typical air tools, I will need a much bigger compressor. A 4-way lug wrench will be a more reasonable investment for mounting tires.
