I'm having mine built now.
Dual Test Patterns in one box.
The builder hates me.
I have no idea if two will even be useable together.
I just know how much I love my single existing one, and Devi would never build me another, and well, after a year and a half, I just said fuck it and had it cloned.
Except if I was going through that trouble...I was going to go to wretched excess.
If one is good, why not two!
