I'm searching for all the variations in the g.i. joe 25th anniversary line?

is there anywhere out there that has a comprehensive listing of all of the action figures, complete with all variations? i've been looking, but can't find any. i know about zartan's color change, shipwreck's belt buckle and tattoo, cobra soldier's gun color, gung-ho's hat emblem, and the hooded cobra commander's belt buckle and gold buckles on right leg. also, i've heard of a yellow-ish stalker. any help appreciated.
