There is a particular reson I want the 508. My mom is wanting to sign up with Dish and she can get the initial 2 receiver deal and have one in her bedroom. With the promotional, her bill will be just a shade less than what her cable bill was (package will consist of AT150 (and yes, it has to be the AT150 because she wants Hallmark channel plus a couple of other that are only available on AT150) and locals). However, after the promotional period, her bill will go up to a little more than what her cable bill was. What I plan on her doing is losing the 2nd reciever and just running a split cable from a 508 ( no DVR fees) to the tv in her bedroom. Therefore, all she has to do is carry her remote to her bedroom if she wants to watch tv in there. I know this doesn't sound like a big deal because she will have much better picture quality and more than double the number of channels, but to todays senior citizens more money is more money and less money is less money, regardless of what you got.
