This is the scanner we use to scan in Gabe's school things. It is a GiiNii. I don't know the model but you can get one that looks like it off ebay for about $60-$80. Looks like new they are closer to $90-$100.
SD card holds the images.
The only downside of ours is that is does not suck through a photograph. Aaron said there is a way around that problem but I was only 1/2 listening! :-)
