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!"
That only does so much though. There is a service port in the back that you can get to with the exception of on the Sharp models. It gives you a lot more to work with. The equipment to do this unfortunately costs an arm and a leg and maybe your first born child, or paying someone such as Steve Jr. to do it. The DVD is an excellent idea still because it does do you some good, but for the full potential you should have someone calibrate your set if you have the money for a set that big then it's a drop in a bucket for a huge return on your set.
