I enjoy giving my games away for free, its fun having other people play something you created.. Get to tell a story for others to enjoy... Something you work hours and hours upon and have people say, "Good Game!" or something like that. (You hope you don't get, "That sucked!") 
One option is to have a demo to download, and then a password protected zipfile for when people pay.
My thought on it though, is that unless you are REALLY GOOD and have clout in the community (like Dave Gilbert), its really tough to sell a game.
