ah, the 20d. i'm using the rebel now as well. i dislike the autofocus on it oh so much. it's so finicky when it comes to taking a picture. it tends to be aggravating. i wish i could use manual all of the time, but i don't trust my eyesight.
sadly, i can't offer advice on the storage device. i've never heard of either.
i dream of someday having as nice a camera as those!
already emailed this, but - I finished the 1st set, do you have another one or two for me, or anything i need to fix on the first one?
