If the ACM has problems, the AFS crew has pulled off the miracle of all miracles - keeping all negative stories about it off of the internet. I've been watching them for years as I've geared up for my build and have yet to hear of any real issues with it. I'll be ordering mine in the next few weeks. A major selling point for me is the ease of installation and future panel modification. That's probably not a big selling point for an avionics shop...
