Thanks Jim. I bit of research and I found out the big difference between the DBK and the DFK is that the DFK has an ir-cut filter over the ccd chip. I know with the DFK you have to buy some firewire cables, but does anyone know about needing a "firewire interface card" for your laptop? I read one might be needed.
