guys I saw this site, that do custom laser engraving/printing or whatever on battery covers, it will be more like the ones that the starwars psp has, from the way it looks like, but I don't know if I'm allowed to post the link, because it's on adifferent language, pilipino/tagalog to be exact... they make really good designs, they can even make the kratos thing on the upcoming GOW bundle.. (other reason why I did not post the link) it may be not allowed on our forum...
-my one more reason to go home.... lol
-edit post-
here you go guys..
