playback tach's

In my challenger I have a Sport comp Playback tach which also has a intergrated shift lite. They don't make that model anymore.
For the Dart I'm building I have a standard sport comp tach,

Autometer makes a Shift lite controller w/ rpm playback module I could use along with my existing tach. about the same price as buying a new playback, just wondering if anyone has used the module?
