always go for at least a .43 to .3 fisheye lens, and if you want them to look pretty good (no black ring marks on corners, like you see all the time) youll probably have to spend 100 dollars or so. my first fisheye was like 30, and didnt have the rings though. Do you know what size your camera lens is?

oh yeah and marc- its 6 40 AM (schools back woot) and i hit the floor laughing. i dont think ill need coffee this morning...
