I would have to agree with Ecomike, scan tools for Renix can be useful but for the most part old school troubleshooting gets it done.
I have the Snap on mt-2500 with all connectors and keys, with domestic and foreign cartridge up to 97'. There is a trans cartridge, can't remember the specifics though. I would have to hook it up to get a list of the live data one can view if someone really needs it. Live data is it, no codes thrown or stored on Renix. Optional printer is available to record data and print. I can use it on obd2 cars up to about 04' as well.
For Sale if anybody really wants one.
