HD camcorder recommendations?

[Mockery]

So I'm looking to get a compact HD camcorder to start doing more web videos with and wanted to know if any of you have suggestions on some good ones to check out. I don't have an exact budget in mind, but definitely would like to stay under 700-800 bux. Here's some of the things I'd like the camera to have:

-External mic input
-Built-in recording light for night footage
-SD card input
-Optical zoom
-Decent built-in mic with solid wind/noise reduction
-Outputs to a format that doesn't require some annoying codec. (.mp4 or .avi would be fine)

Photo snapshot quality doesn't really matter to me since I already have a good camera for taking photos. I've always been partial to Sony camcorders, but I'm really open to anything that works well enough.

Thanks in advance for any suggestions you may have.
