Thanks guys.
We would be employing someone to actually film and edit the content.
I should have mentioned that this camera will not only be used for streaming content but willl be used to shoot footage to be included in cd-rom/dvd based educational software which needs to be broadcast quality. Obviously we'll have to compress the video and audio a fair bit (in FC Pro) to stream it. Sorry guys, was so caught up in the excitement of buying a shiny new camera that I left out the vital information!
I take it broadcast quality cameras can't be bought from your local currys, it's got to be a specialised store? I've had a look through online reviews which seem to only include your average family owned cameras.
Tripod has been added to the shopping list aswell
Thanks again guys, your advice is invaluable.
