I'm in. Haven't participated in one of these before so i figure it's about time.
I was also thinking about the raiden, but I'd have to get a spare. The one I have is set for straight-from-the-show appearance. For those who are unfamiliar with it, it's from the anime "Gasaraki." I have the series on dvd and it has an interesting "what if" element about mecha in a near-future battlefield. The first few shows include a battle sequence of the other guys' mecha tearing into a formation of Bradleys.
The other, more whimsical option I'm thinking about is an EVA Unit 02 in a German armor camo pattern. I figure it would be an interesting change from the usual bright red.
What the heck, maybe i'll do both.
