Where could I find information on video game gear?

Whenever I read a Game Informer or Play magazine, I always take a moment to enjoy the game gear sections. I’m not necessarily looking to buy, but it’s something that interest me. I know that Ebay, Amazon and whatnot have such sections but I was wondering if there is anything more specialized on the subject.

And by gear I mean anything from protective cases for your Wiimotes to Final Fantasy figurines.
