I hope I get a notice when Docsis 3.1 is available in my market.  It doens't make much sense to spend the money before then.

If you need assistance ordering the equipment later please reach back out to me here, but for those customers purchasing their own modem please make sure the device you're buying isn't Comcast owned equipment. Previously rented modems can be used on an account but we will charge our standard $10.00 modem rental fee.

FWIW, With the Comcast rental modems going up to $11 this coming year. The yearly rental fee adds up to $132. So that makes the payback time quicker if you buy your own device. Even the 3.1 devices (mentioned above) which are a tad more expensive will pay for themselves in just over a year and they should be good for a few years to come.

You can run into problems buying used.devices, some of them may even turn out to be stolen rentals. (By the way that is impossible with the modems mentioned above in this thread, Comcast don't rent those). Some may be legit, but still attached to someone else's account, that can lead to problems too.

I would only buy new from a reputable dealer, after making sure the device is on the approved list for the speed I'm on:

If I buy a Comcast-approved gateway, I need one with emta.

And then there is the issue of when 3.1 will be supported in my market (Houston).

At present of course there are no retail D3.1 phone capable devices, but Comcast did say that they would be making the XB6 available at retail. No sign of that yet though. (I'm sure they will be expensive too)!

The current D3.1 modems are compatable with D3.0, so they would still work until D3.1 comes.

I have my MB8600 hooked up and it's synced at 3.1 with 1 OFDM bundle on the downstream.  As for the EMTA you should be able to drop the CM rental fee and they'll keep the MTA on site for phone service at no charge.  All in all it's synced at 29x4 channels and running smoother than my previous modem was on the same outlet.

I have a 2-year contract bundle.  Not sure how I could break that up.  And you went over my head with the CM and MTA bit.  It sounds like I would have to get a separate eMTA to go with the MB8600.  And until I try it, I still don't know whether my neighborhood can support 29x4 (28x4?).

Sadly i don't think there is any DOCSIS 3.1 gateway with eMTA. I'm constantly hoping for one though, preferably from Netgear.

Sorry for the tech jargon..... So, the MB8600 is capable of 32 downstream channels and 8 upstream on 3.0 or 2 OFDM channels up/down.

more channels = more bandwidth and stability

OFDM from what I'm seeing combines the equivilent of 4 channels into a single larger channel. 

Equipment isn't part of the package pricing..... Sure you might get a discount on DVR service for the first year but, year 2 it's another $30 or you additional TV's beyond #1 are another 8-10/mo for the box.

The MTA portion of your current setup for phone service is similar to the box ma bell put on the side of your house when the line ran from the pole to your house.  It's required to have the MTA when you get phone over coax.  There's no specific charge in the system for the MTA itself because w/o it they couldn't charge you for voice services.  The MTA/modem would just get turned down for the wifi side and they would move the billing codes for HSD/internet to the MB or whatever 3.1 device you went with.  You would essentially end up with a splitter with one to the MTA and one to the new modem.
