I like Docs advice about a personal site. I feel like that is the best way to go for a hobbyist to make a few bucks. One person I know that has a personal site has integrated it with the payPal, "buy it now" buttons. He sells knives, and every once in a while gets an email saying a knife sold. All he had to do was list it! Not bad. Google has a competing service with pay pal, google checkout. I've played around with it. What I like about it is you can keep your inventory in a google spread sheet, and the store front is automatically generated by google. All you have to do is have the site up, and update your inventory spread sheet. I think it is a good option worth exploring. Currently I'm planning on going that route in the future. Right now I've got other irons in the fire that need attention though... Good topic :)
