My three Men In Mat Black G's arrived today. They are basically everything I hoped for. They are near the top of my favorites at the moment.
Here's the photos and video I promised.

Overall, I can't find anything wrong with them other than the inflated Japanese price. These are easily the most readable negative displays models I've ever seen. They have sort of a shiny mirrored look to them that really pops in most any lighting. The backlight didn't show up at all really when in direct sunlight, but it works well enough in low light conditions.
I wish they would release some more of these. A Frogman one would be amazing. There doesn't seem to be any more coming out though.
