I'm assuming you are looking for a PCI firewire card? I've used several (different brands and chipsets) and the only difference is what video editing software they are bundled with. I've used the ~$22 one www.newegg.com sells several times and it works like a charm.
I need one so I can dump footage from a DV camera which I plan to edit with Adobe Premiere. I've never done this type of computer editing before and so that's why I'm asking for your input/opinions.
Well, then it's up to you what you want to do. You will see superior results out of a card like the DV200 or DV500, or the DV Raptor series, and they come with Premiere. ($200-600)
The cheaper cards will not yield the kind of image quality these cards do, but they do work.
