A $275 Hi8 Camcorder from BestBuy or Circuit City
A $80 Videum video card from ebay
A $10 S-Video cable
And you're ready to roll.
Advantage of Videum is that they will allow you to broadcast 1,2,3 or even 4 feeds at once from same camcorder.
Disadvantage is that it does not work well with Flash cam apps
