If I tallied up all the money I have saved over the years using Pinrepair's information, I could buy about 100 CD's easily.
$10 is a bargain, $50 is a bargain, and on and on.
Clays guides have been a go to resource. And think about all your time he has saved us by having all that great info, so you don't have to reinvent the wheel or spend hours troubleshooting.
I'm gonna order a CD just to show my appreciation.
