card recommendation

[erpo41]

I'm looking for a recommendation for a card (or cards) that will allow me to capture at 8+fps per input on 12 inputs. Not all 12 inputs need to be on one card, but I want to be able to put enough of those cards in one PC to get to 12 inputs per PC. Since a bttv chip can only do 5fps when switching back and forth between two inputs, I think that means I need one chip per input, so 12 bttv chips.

In looking through the hardware lists on this site, I found only one card that offers one-input-per-chip and a large number of inputs, and apparently it's not being made anymore.

Any recommendations for something I can buy now?
