Newegg has the Motorola SB6121 SURFboard Broadband Cable Modem for $77 - $10 off with coupon code EMCXTXW52 [Exp 3/7] = $67 with free shipping. Features DOCSIS 3.0 Security compatibility, maximum theoretical speeds of 171.537 Mbps, and has RJ-45 ethernet and 75ohm F-connector interfaces.
I bought one for a much higher price. If you get a DOCSIS 3.0 modem remember to place it at least a full foot away from your Wireless Router or you will experience interference. I couldnt even stream a 720p movie after installing this and then put it further away from my router and boom! No more problems Hope this helps some out there...
Great reviews and supported by most ISPs.
