I am moving and switching to cable for Internet. What DOCIS 3.0 modems
are good? I will be supplying my own router so just need the modem.

The company will be Cable One if that matters

I've found the Motorola cable modems sold at Costco to be reliable and
dependable.

That's what I bought. It's also what Comcast sells at their stores for a
little more than what Costco charges.

I live in Charter territory now. No Comcast handy :-)

Motorola/ARRIS SB6141. Costco has them new for $75. Good up to
DOCSIS 3.0. It does SNMP v2 and v3 but the Comcast firmware doesn't
let me access SNMP. The generic firmware might. I've had one failure
out of about 8 modems so far and that was a blown power supply. Beware
of used modems as Comcast seems sloppy at releasing the MAC address
from their database when a customer pulls the plus with an owner
supplied modem.

It appears that Costco doesn't carry them any more :-(

The SB6141 seems to go up to 100 Mbps.

The SB6183 is supposedly for 300 Mbps

They were in stock in Santa Cruz as of the previous Friday. Tahe
SB6141 disappeared from the web site some time in February. I have no
clue what's happening but I am buying them regularly.

Umm... check your numbers please:
<http://jamescausian.hubpages.com/hub/Arris-Motorola-Surfboard-SB6183-latest-and-fastest-cable-modem>
Also note that upload speed is 131 Mbits/sec for both models.

There were some really awful firmware bugs in the SB6183 when it was
first released about 1 year ago. I'm not sure about the current
status as I haven't used any of them so far. It seems that the
People's Republic of Santa Cruz pissed off Comcast a few years ago and
now Comcast is retailiating with half the speed the rest of the SF bay
area is getting. No need for the SB6183 until we go over 150
Mbits/sec.

Note: If you're deploying MoCA, definately get the SB6183 because of
the built in MoCA reject filter. I've had problems with the SB6141
and MoCA and had to design and build a 1GHz diplexer to fix it.

I bought a Motorola 6121 because it was on the "supported" list at Comcast.
By the time I received it, the list included the 6141.
The 6121 is cheaper, and has the same speed as the original Comcast-supplied
router/modem/hunk-of-junk.

I was disappointed to see that the motorola modem says Arris on the
outside, but it doesn't seem to have seeped inside yet.

router/modem/hunk-of-junk.
Both the 6121 and 6141 are on the Comcast supported list. The price
difference is $15. The main feature difference is the number of
bonded download channels:
download upload
6121 4 4
6141 8 4
6183 16 4
Any of these will work with download speeds up to about 105 Mbits/sec
(Comcast Blast Plus). Any faster download and you'll need more than 4
download channels. I've been pushing the 6141 because it's fairly
future proof and because Comcast is dragging it's feet on doubling the
download speed in Santa Cruz for reasons unknown (or at least
unconfirmed). I also want to stock one modem, not three. For $15
more, the 6141 seems like the right answer (this week).

However, when DOCSIS 3.1 arrives, everything changes again. It's
likely that DOCSIS 3.0 modems cannot (or will not) be upgraded to 3.1.
So, once again everything goes to the recycler to make room for the
latest greatest. Meanwhile, the few 3.1 modems that are available
will also work on 3.0. With 24 bonded download channels, it can do
about 900 MBits/sec (Netgear and Hitron).
<http://www.hitrontech.com/en/newsroom_detail.php?id=36>
With 32 channels bonded, about 1.2GBits/sec.

I recently got involved in a Comcast gateway transplant moving up to
the new Gateway 3:
<http://customer.xfinity.com/help-and-support/internet/wireless-gateway-3>
So far, the performance is great and much better than the old Modem 2
(with no change in service). Getting 135.70 Mbits/sec download and
12.10 Mbits/sec upload in Los Gatos. The dual band wireless also
seems more stable. It's been up for a week, with no irate phone
calls, so I guess it's working.

I think I am going with the 6141 if I can find one at Costco in Arizona
as I move there.

If that fails, I will do a 6183

Cable One (the ISP) says they "support" both.

Anyone have any VOIP problems with either modem?

Cable One publishes a list of preferred modems:
http://support.cableone.net/app/answers/detail/a_id/780/~/which-cable-modems-are-supported%3F

The list is dominated by Motorola products. This is a good thing.
Those modems are OK.

I have owned three cable modems so far. They all lived for about 5
years. The first was an RCA, the other two were Motorolas.
