The real benefit, IMO, is in the bundled packages that they offer with the T2Cs.
I hear a lot of complaints about the grid based graphics, but it really isn't that bad. i've only done one so far, but it hasn't had any problems at all. I had another sold, but now we are doing Prodigy instead at the same price (actually a little less).
The T2Cs doesn't have a Zigbee option, so only 433. The rez is the same as teh T2C, but the screen is slightly smaller. It uses the automatic PAGE (control pages) layout, similar to the T2B and M2, which is probably the one really annoying thing to me.
The grid definitely sucks compared to the T2C, but for the price it is an easy and good upgrade, IMO from a T2B.
