have thought about it before Mark did, and you should have contected Richmondgears and had them manufactured, so that you could have sold them to us for $190. It takes a lot to what Mark did, time, money and personal time. Whats sad is that when someone does something good/nice to the Z community, some of us tend to question it. Im planing on getting the gears, and i hope most of ttz owners do.
