I bought an RCA Cablemodem about two years ago for $100 off of E-bay, back when they were $250 retail. E-bay for Anandtechers is like masturbation for Anandtechres - you all deny doing it, but you need it, use it, and love it more than the rest of the population!
Own. Motorola 4100. Have had absolutely zero issues or problems with it. Will lose signal once in a blue moon during thunderstorms: simply power down, power back up and all is well again. No way would I ever pay to lease one as you'd have paid for the damn thing in a year or so.
