laser points are very fun to mess with people with, especially when they aren't expecting you to have one. but i've only seen them at gas stations, and they run about $5 there
Check ur local dirt-mall{Fleamarket}.The chinese people at mine get all sorts of stuff shipped here and sell it cheap.They have big boxes of them usually with a nice assortment of the things that make little pictures{I.e. crosshair,dot,ufo,etc.}
