Grubb, I *think* it was you that had the cool tire gauge/deflator that pulled the valve stem core and allowed you to check the pressure while deflating. If so, do you know where you got it from(IIRC you said it was a present from someone).
If anyone else knows what I'm talking about, please feel free to chime in.
Quadratec has them for $24.99. Or you can buy a "Currie" one that costs $5 more, but is otherwise exactly the same. Or you can buy an ARB version for $32.99, again made by the same company.
I've got the ARB version. Superb piece of equipment and very well made. Still takes forever though. If I had to do it again I'd probably go with a set of Staun deflators.
