It's hard to find a FireWire reader whereas they're the fastest.
I have the Sandisk FireWire Reader,
only in Dutch that's for CF cards I and II.
So I also got a CF Card Adapter to SD/SDHC from
JOBO
It's a bit of a hassle but once you have it, it's fast, very fast. I do all my HD movies with it and they are 300 Gb and more so that's a lot of SD-cards.
By the way I'm a Mac-fan since the eighties.
