Thanks guys. Yeah, the few I found were on auction sites, and they appear to be industry standard equipment like the Arris models Comcast uses in the Gulfsouth region. I figured someone moved, kept their cable equipment, and decided to make a quick buck. Oh well, I guess he's saving enough by switching service providers to justify 7 bucks a month. At the rate technology moves these days it will probably be less than a year before a retail version is on the shelves at Wal-Mart.
