FireWire Interface

Hi, I'm relatively new to the world of recording, and had a question that if answered would make my life a little easier. :D

So, I have an M-audio 410, which has 2 preamps.. Which essentially means I can record 2 tracks at once correct? I need a Firewire interface that can track 8 channels at once. I'm having trouble locating any that are rated well and are affordable. any ideas?

Thanks.
