Wow thanks for the heads up. I would have been VERY disappointed to have purchased one of those and not get the fisheye distortion.
After a long evenings research (you have got to love google!), I have found a few lenses that can distort for the APS-C (1.6x crop factor, for Canon). A lot of them had rounded edges though (not what I'm after) so I found two which didn't have the rounded edges.
Oddly enough they are both 10mm but give a massive field of view and distortion. The first option is the cheapest, and is the Tokina 10-17mm f/3.5-4.5 at £400. Lots of people seem to use and enjoy. The second option is the new
Sigma 10mm f/2.8 EX HSM at £450.
This will likely be my option as it's lower f value, and a prime (I want a fisheye for distortion, so zoom is pointless taking out of fish eye).
Anyway here are a couple of links to a blog where a guy has taken some photos using the sigma 10mm fisheye, looks like with a 30D:

Looks ideal to me. Quite expensive but I think the Sigma EX are good?
Once again thanks, I just assumed any low mm lense would distort like a fisheye. You saved me making an expensive mistake
p.s. mole - those are some AWESOME photos
