Black Magic Deck Extreme vs Kona LS for PCI

I'm considering a Kona LS or BlackMagic's Deck Extreme for use with a Mac G5 Dual with FCP Studio 2. I'm migrating up to HD but need to keep good quality (analog) SD as I do so, and I'm wondering what I should be considering to make a choice between the two.

One question revolves around this statement by Kona:

"Using superb quality 12 bit video A/D and D/A converters, analog formats like BetaCam SP have never looked better."

Blackmagic does not mentioning 12 bit video for analog, but does mention "...true 10 bit..."

Whichever I choose I need something that will fit the G5's PCI slots.

This may not be an issue and there could be other issue's I'm not aware of... and I'd appreciate any guidance in this arena. As I am primarily creative content (not technical) I just don't know...

Thanks
Dennis
