Drew, I want to build that one as well. It seems like the perfect balance of cool looks, functionality, and cost. While you are waiting, you might just want to order some upgraded signal caps, the power supply caps are great as they come from the factory. Shouldn't be too expensive at all, and my experience with their kits is that better caps are a genuine enhancement. There is lots of info on the Bottlehead forums about that.
I e-mailed Eileen over the weekend to get a new transformer for my Foreplay III extended. I told her it was not urgent. I'm sure she'll touch base this week.
