I'm waiting to see what Eutronix comes up with on buttons. He's gone through a lot of hassle to get this far and I'm willing to wait to see what happens.

Just so you can add my numbers to the total count against Mark's projections. I'd likely wind up with 2-3 sets of blue, smoke, and UV reactive buttons. (I'd hope that the UV reactive could be done combined with the smoke and blue so that they'd be smoke/blue in daylight and glow in darkness)
