hello, I am looking for a switch box to plug 2 cameras into, using 6 pin firewire cables, then from the switch box to the computer. I am starting a live internet streaming show and need to switch between cameras on the fly, without the computer "seeing" that there was a switch so it doesnt drop the connection. I have found a few 1394 switchers, but they are in the 1000 to 6000 dollar range, that seems ridiculous. I have found that the box needs to be "syncronous" so that it can flip between the inputs and not drop the connection. need some help !
