I have done a good amount of research here, but still haven't found a definitive answer...outside of accent colors (red vs tan), are the gw9400bj and gw9400-3 different negative displays? It looks like the digits are different colors (grey vs tan) Is this correct? I'd like to put a negative module in the camo version, but I like the pictures of the gw9400bj negative displays better than the gw9400-3. They seem more crisp. Any feedback is appreciated.
