It depends on what you are looking for and what your price range is. I use a suitcase style compressor that you can get from harbor freight or home depot for under $100. They are not to expensive, small and easy to move around, and are great for cleaning off your rigs. Mine peaks at 135 psi and has a 1.75 gallon tank. It also has a place to keep all of your attachments so you don't have to store them elsewhere. It works for me and quite a few others that use it at the track on race days.
