I switched from E* back to Comcast when the HD packages and the 622 deals were announced by E*. I got a 32" HD Panasonic LCD and was waiting for E* to make their announcements. No deals there, so I went to Comcast. My biggest deciding factors was that E* would not have my regional sport net anytime soon in HD and $299 to buy the privilege of leasing a 622!
The analog channels on the LCD are not good (but with HD, I'm really not watching much of anything else anyway). In fact they are better on my old CRT. The digital channels on the LCD are equivalent (to me anyway) to the SD on E*. The HD stuff can truly be spectacular, even my low tech wife was impressed and can now see why I wanted HD programming so badly.
The 6412 DVR is just OK. I liked my E* 522 much better as far as capacity and ease of use. The 6412 is not as intuitive as the 522, at least IMO. I didn't like the 6412 epg at first but I'm used to it now and kind of like it. I love the fact that with the 6412 and HD, most of what I am watching is DD5.1 with my receiver and surround set up.
I did like E*, never had any bad service, etc. But overall I am fairly pleased with Comcast

. With the buyback offer I pay like $44/month for digital plus and DVR. Even when the price goes back to normal it will still be cheaper than the equivalent HD package with E*.
