HaTcH's site is Liger's Union:
http://www.bearcreekfire.com/zoids3d/ Hidocker's site has pretty photos. My brain's too dead to remember more model sites...
http://www.smeat.net/zoids/http://zoidsfront.main.jp/ Armor Dreamland, the best battle story resource site I've found, with cool fanart and stuff too. All Japanese, but that's what Excite's for.
http://www.geocities.jp/hanegaru10suki/hp002_001.htm Do you still like Zoids 10 years later, formerly known as Zoids Corner. Release dates and pics for...everything, really.

Um...I'll find more later. Those came to mind immediately.
