Remember that you also need a standard RF, a silenced RF, a variable silenced RF and a 55g RF.
Since I had a Filco with blues, an IBM Model M and a Choc Noppoo Mini with browns, I thought I would be coming full circle when I got my HHKB black and an extra set of black keycaps.
But the problem is all I could think about was "Oh now I wan't a Realforce board", "That white HHKB looks so damn sexy" and the result is that after spending hours lusting after those two keyboards, I bought them.
I should be getting them tomorrow. I totally don't regret it. After completing my order on EK, I thought I might have made a mistake. That lasted about five seconds!
Right now I think I will stop there (except for keycaps), but then again, I thought I was going to stop after getting my first board, the Filco.
