I also use Viddler to upload my videos. YouTube has length restrictions. I am using video on my JV page and as part of my teaser content.
Regarding cameras, etc. I have the Logitech QuickCam Pro 5000 and a Samson C01U USB Studio Condenser Mike.
I also found this really cool over-the-web-cam telepromter from a company called Bodelin. It is called the SeeEye2Eye and it is just awesome. Having the teleprompter enables me to make longer videos with ease, and I am looking right into the camera the whole time.
