I got a 40GB CF reader/drive for $40 on FredMiranda. The old ones go for cheap, but they're not solid state so be careful.

Honestly though, I'd just get a bunch of memory cards, even with those gigantic 5D2 files. On your honeymoon I doubt you'll want to be telling your new wife "oh hold on, let me just transfer over all of these gigabytes and reformat my card, be right there!" Plus CF cards are more durable than anything with moving parts.

edit: You can borrow the drive if you want, FWIW. I never use it except when I'm traveling.
