Hey everyone,
I wanted to post a link to a site that has some decent fish eye lenses at very cheap prices. Of course they are not the quality of Canon or Nikon but do a pretty comparable job and are very fun.
They are Russian fish eyes and can be bought here at http://www.rugift.com/. We have one here that is 16mm, I would go for the 8mm personally. You have to adjust the apeture and focus on most of these manually, and they come with converter rings to fit what ever camera body you have (you just have to specify when ordering).
Check out there site, they have a small gallery on flickr if you want to see some of the other images they produce. Again, you will pay over a $1000 for Canon, Nikon, or even Sigma for a good fish eye. Rugift sells theirs anywhere from $200-$400. Fish eyes are not the first lens I use when reaching into the bag, but this is a good deal and worth the price if you just want to have fun with a fish eye.
Hope this helps you all.
Shad
