Hi Eric, I scan a lot of leaves and after going through a few of the professional (expensive) handheld scanners I've settled on the Canon LiDE 110 scanner for leaves I can bring back to a lab/field station. It plugs right into the USB port of a laptop. http://www.usa.canon.com/cusa/consumer/products/scanners/photo_scanners/canoscan_lide110. With the right macro script in ImageJ you can calculate whatever you need in a hurry.
For more portable stuff I've settled on the VuPoint magic wand, it's battery powered (http://www.vupointsolutions.com/magic_wand_portable_scanner), micro sd with card reader. This one's great for measuring leaves in situ (i.e. for measuring herbivory rates on same leaf over time). What you want to avoid are paper feeders since thicker leaves won't fit into the paper feeder and smaller leaves are impossible to pull through.
