I've had an Edge w/CableCARD and the newer Tivo Mini 4k or whatever it's called connected through Moca now for probably 6 months and so far the setup has worked flawlessly. I wouldn't have given that good of a review of it as downloading from it using KMTTG didn't work until about a month ago after they finally issued a patch for it (even though it's an unsupported feature).
The apps on the Edge are junk though...basically all you're getting with the Edge is a snapper version of their OS. The Mini 4k is also a lot snappier over the older Mini (which I also have connected to the setup). The apps though, launch as slowly as they did on the Tivo Premiere or old Tivo Mini and Plex hasn't been updated at all...they also don't offer some of the latest streaming apps available, so do not buy the Edge for the apps.
This late in the game though with the future of Cable being a little uncertain, I'd probably just find a good cord cutting solution...this is my 3rd time with a Tivo (had one initially, then went to Windows Media Center, back to Tivo, then did cord-cutting for awhile using Plex and an HDHomeRun network tuner, now back to Tivo with the Edge model. I'm guessing that I won't keep this Edge setup around for more than a year and a half as my cable provider is discontinuing RF-based cable TV and going to an all IP-streaming type of setup, so beware in case your cable company is going to do something similar soon.
Had I known that my cable provider was discontinuing the RF/CableCARD support, I would've stayed with my cord cutting setup. My only problem with cord cutting is the wife had trouble finding stuff vs. how the Tivo keeps everything in an easy to get to spot.
