Since i'm not finding Uzebox ( http://uzebox.org ) in the prods hardware list, where can i find them? and how good is the oppinion from all people from demoscene about hardware like this?

Find Uzebox demos? I guess you'd need to be the first one to actually make one... good luck and tell us how it was :)

There are some productions for obscure custom hardware. Check out, for example, Craft.
