Let the hive mind of Engadget get that for you.
"I need help! I want a small pocket camcorder but I'm not sure which one to get. I don't want to fall into the hype of the Flip because I worry two hours won't be enough. What should I be looking for when considering a small camcorder and where can I get a good quality one with expandable memory? Thanks!"
Right now, DirecTV is ramping up to offer the most HD nationwide. But the other guys aren't exactly sitting around. My advice is to wait until you're ready to buy, and then compare the HD lineups available to you, and see which you like.
We are currently in a time of transition; new HD channels are being launched and picked up almost every week, so now would not be a good time to make any commitments to any particular service provider.
