Depends
This has been discussed a bunch. Depends if you plan to paint yourself. Also how many air tools you plan to use. Air sanders and die grinders and such use a lot of air. Painting takes a lot of air. The rivet tool does not take much air.
I don't know how someone gets along without a compressor. For tires, toys, tools, general cleaning. You can likely get by on a small 1 - 3 HP single stage. If you plan to sand or paint, maybe a 5 - 6 HP single stage can get you by. You can still buy them for in the $400 range, so don't cut yourself too short and wish for more later. Not too hard to sell an air compressor.
