I like that idea. if its out of your house the overhead should be very low other than for some stuff but one could get or find others that have stuff they would like to sell off or get rid of they could put in your own garage store. You could even have tubs of parts for sale like one I use to go to years ago that folded in St. Louis,MO. called(Highway Hobbies) owners name was Roy Bean...real nice guy as builder himself. Id love to have a small shop here to go to as well but with a Hobby Lobby in town all of the ones we had closed up...bummer.
