keyword lists - anyone use JP Dodel?

I am building my new website and want to correctly include species in all images' metadata keywords.

I know quite a few people use the MarineLife list which costs $100 from http://keywordworkflow.com/products/marinelife/ (with 5% off if you use the WetPixel offer code listed at http://wetpixel.com/i.php/marinekeywords, although the link from that page is incorrect)

I have found another list that is significantly cheaper at $20, and wondered if anyone is using it and can comment?

The purchase page is at http://www.jpdodelphoto.com/keywords/

it seems like the Dodel version has only fishes and no invertebrates, but I have no direct experience with it.
