I've actually been impressed with some of the smaller compressors for occasional air tool use. I've got a portable 4.25 gallon that, before i broke it, did a great job running most things. The key is finding one that has decent power and CFM. Some of the small ones put out reasonable CFM. Don't expect to run paint guns, but air tools should be fine.

*edit* and if I get my little one running any time soon it'll be up for sale. It's something stupid gone wrong, but I don't have time to pull it apart just now.
