Turns out the Motorola SB6141 and the SBG6580 are the only two in Texas that are "certified". Well of course I tried to purchase the SB6141 on Amazon but they are out of stock. I've looked everywhere else and it doesn't seem like anyone actually has or ever has sold it. The SBG6580 is available but I don't need the WIFI because I already have an airport extreme.
I bought one from these guys
a couple weeks ago when they were still $99. Although you can find a few auctions in the $150 range, at this point unless you're on the Extreme or Ultimate tier you're better off getting a cheap D2 modem and holding off on the 6141 for a few months.
