Other than the Integra Research RDC-7.1 what other prepros use Apogee for master clock?

I love it that people are looking for features in a ~$1000 prepro that are in a $5000 prepro.

Outlaw has to make compromises somewhere or increase prices. Although it would be interesting to see them make a no-compromise piece, I don't think I could afford it even with the Outlaw discount.
