In my area, Comcast charges $6.75/month for their HD with local channels only. I guess they give you a set top box with that. I don't see any need to pay for that package when the DTB-H260F will do the same thing by getting less compressed ATSC OTA, or decoding the QAM off the analog feed. I figure the $180 Samsung will have paid for itself and start saving money after a year and 3 months.
The Digital Classic package at $55.64/month gives you the HD channels ESPN, ESPN2, TNT, Discovery, MTV, and NHD1 in addition to the local HD channels. I don't watch any of those other than my occasional nationally broadcasted Hokie game on ESPN or ESPN2 in the fall. It's not worth paying almost $700 a year when the majority of my viewing is primetime shows that are OTA.
