I too 2nd the dslreports thingy.
give ya a good idea of what is avail, speeds etc.
I had analog cable FOR YEARS, until just recently made the move to digital and I am impressed, while there is some pixelation during very high action scenes (almost like watching streaming video when it has a small hiccup) it is really nothing you would ever notice or bother you but I have seen it a few times. I have Time Warner and like I said so far so good the on demand channels kick ass, and I do have the option to go with HD too, now if I could only talk the gf into letting me get that big plasma screen
oh wait I am the one that keeps telling her they cost too much still
