I'd be grateful if you would kindly advise me about which camcorder might be best for my needs - there seem to be so many out there!

I want to record teaching seminars in average size rooms, there would be about 30 participants in the seminar. The main necessity is that the camera would have a mic in jack so a wireless lavallier microphone can be attached to the presenter for good sound.

Hard drive or SD card would be convenient for storage. Price range is a maximum of 500 euro.

Thanks in advance for your kind advice.
Best wishes,
