Recommendation for budget hd camcorder (w/external microphone jack or great audio) for new youtube channel

Hello everyone,

I'm searching for an hd camcorder that either has great onboard audio capabilities or that has an external microphone jack. I would like to keep the budget around $100 or less. Let me know if you have any suggestions.

I have been looking at the Kodak Zi8, but I cannot find any for a good deal, and have since read some reviews that were negative. So, that being said, I am looking for alternative camera choices. Thank you in advance.
