I've had pretty good luck with the Motorolas. My parents had a sb4200 for about 10 or 11 years. Then came the letter from Comcast that they wanted to send a new modem. Their service is for 12mbs but still had the docsis 1 modem. I really didn't want to change as I didn't feel the speed was worth the trouble and the 4200 never causes problems. Comcast didn't want the sb4200 back and the rental was now like $7/month which makes that 4200 cost more than $500 over the years. So I figured that now was the time to buy a modem. That was the sb6120 that I got on ebay. I did 9 days of speed tests with the 4200 and was getting about 4.5mbs down. I put the 6120 online two days ago. It kicked it up to about 6.1mbs. The tests were all done to the local Comcast server. Tests to servers outside are in the 3-4mbs range. So was it worth it for the extra speed? Not really. But I got the modem for $56.17 including shipping »www.ebay.com/itm/190612289244 so if it lasts 8 months, I'm ahead of the game money wise. I figure I will keep the 4200 in case the new modem dies. I could try to get Comcast to put it back online (the 4200 is on their blacklist). It would give me time to look for a new modem without having to spend top dollar at some local retail store.

As I understand, any Motorola 4xxx series modems that are removed from an account would have a slim to none possibly of being re-provisioned on Comcast's network.
