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!"
I'll admit, the ads are full o' crap (at least wait until you've rolled out your "100 channels", or at lest my GD HD locals), but I have to say - I've been quite pleased w/ my HD quality from DTV lately - especially HBO. Maybe they improved the signal behind the scenes to offset the lawsuit or something? Also - count me as one who has had little issue so far w/ his HR-20. Maybe I'm lucky?
