duide you can get a REALLY good "fisheye" for around 50-60 bucks. It is more of a super wide angle, but they claim it is fisheye. Kenko makes a really good one, 0.53X super wide. I just put one on my Canon ZR 90, bought a step up ring, and the thing works like a charm. You can get out some of my recent videos to see the effect, we use it almost off the time. Mind you the quality goes down the shitter when uploading onto NS but youll get the picture.
hope that heps, PEACE
