It's awesome to be able to "rule out" one of the biggest variables - temperature - in development.
Do you have one you are trying to get working? Or is it something you were thinking of picking up? I ask because the CompnTemp from Curt Palm is an awesome alternative to waiting for the genuine Zone VI article to turn up.
Hmmmm! It's interesting you two mention the Zone VI, I have two of these units I don't really plan to use or keep.
