Thanks, Tim. I had been looking at the ones on
B&H and Amazon. You are right, some are VERY expensive for what they do. They also have very mixed reviews, which is why I thought I would ask here if anyone has had any experience with these sorts of devices.
To answer some other responders:
This trip is with a few friends and isn't photography driven, though I am hoping to shoot a lot and build my portfolio. For me, for this trip, I'd rather not bring my slim but new and expensive computer with me and either worry about it being left in my bed and breakfast accommodations or lug it around with me. Perhaps the next trip I won't be as concerned about that. I will have my iPad, and I can upload some photos onto it and post them, but it's older and super slow and not really a suitable back up.
I did look at the Canon Connect Station, though what I need it for is not really the main function of it, but I guess that doesn't matter if it works for me.
I do plan on shooting to both CF and SD cards simultaneously. I did want to have copies of the images somewhere else, as you would a computer, but perhaps the two cards is sufficient.
