I am still doing some of my own builds too.
I am running this daily now. Be sure you update to a newer build and flash Gapps when you update.

Rom Slot 1 only and 4.2 Gapps
01/06/13 - Keyboard lights (look for the build that says "keyboard lights" in the notes)
01/19/13 - Black call screen fix by Hashcode, fixed a few other bug
01/28/13 - Tether fix
This is heavily based on the STS-Dev Team (hashcode-dhacker29) and the liquid team sources. So a big thanks to them and to cyanogenmod, also to users fattire and redflea. Without their work-sources I will never have even tried this. This still has the same bugs as the other 4.2 roms.
You can find what modified code I used on github here: https://github.com/jsnweitzel.
As usually you are responsible for whatever you do to your device.
