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 vote for ED as well. While past the price now due to a hike, you can often find the MFW-15 for under $500 from AV123 if you look for a B-stock model. So, a slight imperfection, but after listening to my friends Dual MFW-15 setup, they'll knock your socks off.
