You really prefer the CMM? I use to have tons of issues with CMMs losing sync, losing power, dying. It seems to me like the sync injectors are a fraction of the cost and are almost an 'install and forget it' type of product. They just keep on working. I actually prefer the cheaper version that Packetflux offers, having used both extensively.
