I'll add my since I have both.
I've owned a large garage size compressor for years. It is noisy, expensive to run and sits out in the shed. If I was to run a hose to the house, during the winter the air would be ice cold and my electric bill would be climbing. Plus the compressor is loud enough to still irritate people.
So my wife an I discussed our options and tried out some of those smaller contractor or home owner size compressors at Home Depot and Wal*Mart. Still way to loud to concider bringing into the house for arts & crafts work. Yes, my wife got involved with AB'ing too. So we picked up a really quite hobby compressor with an air tank. It might have cost twice as much as some of those bigger ones found in the local department stores. But we have piece of mind knowing one can spray while the other watches TV and the kids fall asleep at night. It doesn't cost much to run either, less than one of my fish tanks. Oh yeah, plus we can easily pack it up with our modeling supplies when we go on a trip to visit family for any length of time.
During the summer days I can still go outside and make all the noise I want with my big dog compressor and airtools, my old truck loves it. But in the house... whoaaa... gotsta keep mama happy and my migranes away.
