Bests & Worsts Reviews from Amazon

After being placed on hold for 10 minutes with technical support, I was informed that Comcast wouldn't activate it because I didn't buy it from an "authorized retailer". The interesting part is that Best Buy is the ONLY authorized retailer. I asked the tech support rep if it's an issue of trust with the Motorola brand (counterfeiting, shoddy equipment, etc...) and he just towed the company line and said, "sir, I'm sorry, but you need to purchase this from Best Buy and not Amazon.com". I was flabbergasted. As of the writing of this review, Best Buy is offering this same modem for $30 more than Amazon, and Comcast just raised their modem rental fees from $5 to $6.61 in my area. I can't help but wonder what kind of profit sharing setup they've got behind the scenes. This feels like marketplace manipulation, collusion, or some other anti-trust lawsuit waiting to happen. I'll probably try to call back in another day or two and claim that I bought it from Best Buy. Maybe I caught a tech support rep on a bad day. If not, this modem is getting returned. I just wish Comcast didn't have a monopoly over my cable/internet service -- I'd drop them in a heartbeat. EDIT: As posted below, I was able to successfully activate the modem via Comcast's Online Chat Support.
