a 30 gig model. It's worked great for me. I also bought the companion extra battery backup. It's the size of a pack of ciggies and can run the Super DigiBin when the rechargeable battery inside the Digibin starts to run low. I also bought the companion ac and car adapters.Or were they included? Can't remember.
I got them because I ain't taking any chances and I have 5 256mb cards and a 512. It usually takes a minute or two to dump a 256 in the Digibin and maybe 3-4 minutes tops for a 512.
The only thing is that it doesn't have a viewer. I was warned that those really eat up battery power on these "digital wallets" or "Image tanks".
I'm still looking for a laptop. To me, being the hopeless paranoid, I'd prefer to burn a CD off a laptop just to make sure.
However, when shooting outdoors, the digibin is much lighter and can strap on to your belt. And 30 gigs? It'll hold thousands of images.
