PS3 Capture Card Suggestions

I've been looking for a good capture card for some time now but i cannot find one!!! I've been looking for one that records onto a USB or other harddrive rather than onto a laptop... Anyone have some good suggestions for a capture card that can take footage off a ps3 and store it on itself?

how about a pinnacle capture card? I never tried those, but apparently they're the best in the market. I use a TV tuner PCMI express card.

I've seen the PVR in action and it looks great but I think you need a direct connection to a laptop... which i also don't have. As far as the Pinnacle.... does that capture onto an internal memory or does that need to be attached to a comp/laptop as well? How about your Tuner PCMI card?
