I guess this could be worth it if your ISP has greater than 5 or 10 Mbps upload speeds.

Actually the SB5100 is arguable the best cable modem available. I was using a Toshiba PCX2500 but notcied that I was suddenly seeing a lot of latency, especially when gaming, at random intervals. I live in a new home that is wired w/ RG6 Quad and there is only a single 2-way splitter in the attic. The cable modem line connects to the -3.5dB side of the splitter, and the other side runs to my bedroom TV. The main feed runs from the attic out to the pole which is roughly 75ft away. My line is connected right in front of the amplifier. Cox has always stated that my signals are well above average, however they could not tell me why I was experiencing latency, especially since my download speeds were dead on for my 3000/256 connection. I then gave up on tech support and decided to pick up a SB5100 from Office Depot since it had a rebate. Since I've switched over to the SB5100 it has solved the latency issue.

SB5100 has well known low upload rate problem, at least with Comcast. Your upload rate can be at around 100kbps when your upload max is 256 kbps. After you switch to another brand's modem, the upload went back up close to 256kbps.

Oh and P.S.: I have 0 problems with upload. I'd be willing to bet its a Comcast problem and not a SB5100 problem.

I have setup up a handful with Comcast and have not had any problems.

Would I see much difference in latency switching from an SB4100? Also, when cable modems are swapped out do they need to be tuned by the cable company are can they just be swapped? Thanks..

You generally have to call your cable comany and register the MAC address of your new modem in order to get it to work, since I think they use MAC filtering to turn the service on and off to different households in a neighborhood.
