Penn,
consider adding to Links too:

www.aquabid.com/

This is like the ebay of aquatics

Looks like a good link. If you look in the user menu, you can submit links. They won't show until I have published them (don't want anyone submitting porn do we?) It saves me having to put in all the information if people do it themselves. I trust your judgement so just add links as you see fit.
