TEAC/Esoteric P700 Mechanism

Can anyone tells me which CMK is this transport is using and how reliable it is? I'm planning to get one from the used market and I think chances of gettin one more than 5 yr is high. So got to make sure parts are available and the TEAC customer service guys are helpful. Thanks for reading guys.
CMK 3. Maybe the 3.2 depending on which year it is. This is the better Mechanism with the lead clamp. Much better than the CMK 4 used on the VRDS T1 transports which have a plastic/resin clamp. It is very reliable. Teac has the parts for it. It uses a Sony laser mech. modified by teac As far as I know.
