I just ordered my own B-stock to be built, but I’m always looking to see what’s out there.
This is what I found today.
Both seems like they could be risky investments, but oh what colors! I’m not sure I ever saw that gorgeous Blue offered on the market . . . buyer beware, a guitar that has not been tested and exposed circuitry seems like a big risk. 
I’m sure you could get Moog to install the circuitry in the Scarlet flame . . . for a price!
