Nice work pgitta!

You might consider adding a page so visitors can submit kits for you to save you some work. I would set it up so you have to approve the submissions before they are displayed on the page so you don't end up with junk on the page you don't want. That should save you a bunch of typing and I bet all the fine folks who visit RCU would be happy to help you add to the list.

One other item you may want to add to the page is a checkbox or something along those lines to indicate if a kit is out of production.

Looks great so far!
