The best deal that I've heard of so far (and the one I signed up for) is the "dish buy back" deal. You get $25 off your monthly bill for 16 months. I got the digital silver package, HD dual tuner receiver for $5/month, DVR for $10/month, and a second SD receiver for another $5/month.
My total bill w/o tax is ~$63/month.
So far I'm really happy with the service. Be warned, however, for the HD Receiver there is a settings menu that can only be accessed while the receiver is powered off and then hitting the "menu" button on the remote. In this menu you can set the desired output resolution, native aspect ratio, and how the box will treat 4:3 signals (e.g. stretch it, leave it alone, or upconvert it to 480p, etc). The installer never bothered to talk about this menu to me......so when I first started watching I was thinking comcast was a sorry, sorry alternative to VOOM. Since finding and fixing this menu, however, I'm very pleased with the PQ. That, the HD-DVR function, the dual tuner, and the OnDemand features all have me pretty pleased with my new post-Voom choice.
