Jan 23, 2013 the local Comcast TV provider is changing over to all digital TV. I have three standard definition TV's that I will replace with HDTV's. Comcast wants $9/month for an STB or $17/month for an STB with DVR, either unit which connects between the Comcast cable and the HDTV(s). I believe I should be able to purchase my own STB's and DVR's at significant savings, but I'm not sure about this . . . can this be done? If so, will someone recommend an STB and an STB with built-in DVR that I can purchase which are both reliable and reasonably priced? Thanks in advance!
