"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!"
Wow, very high price. When I signed up with Dish Network, I got the 622 dvr which takes about 35-40 hours of high def. This costs 5.00 a month and the dvr was free with installation (no fee like Directv charges). Then I paid a one time fee of $30.00 and that enabled the external hard drive feature. I now have 3 500gb hard drives full of hd movies and some specials (number of hard drives you can use is unlimited), much cheaper this way.
The only problem with storing movies like this is that any drive can fail at any time. I had a friend lose a Seagate 750gb drive full of programming, and Seagate could not repair it, thus my preference for owning a hard copy on and and blu-ray.
