I want to buy a fish-eye lens for a nikon D60?

I have the origional kit lense if anyone knows what that is. I'm just wondering what sized thread I need to buy and what to recommend. I'm look for a low end <$100 attachment.

The filter thread on the kit 18-55mm DX lens is 52mm.

Something like this would work: http://www.adorama.com/...NFE52.html

It's $39, comes in the 52mm size and is a 0.42x optic so at the 18mm setting on your kit lens you might get a perfectly round image!

I think you should go with Opteka 6.5mm f/3.5 Manual Focus Aspherical Fisheye Lens for Nikon D3X, D3, D700, D300S, D300, D90, D60, D40, D5000, and D3000 Digital SLR Cameras
