I used to work in an archive, and the Symbol LS2208 was a pretty great scanner. The model is also old enough, that you can find them branded Symbol, Motorola, and Zebra. I had my own cheat sheet to reprogram it, eg. changing the final character to tab or enter, scan on trigger press or always scan. It struggled a little with black barcodes on navy blue labels, but that's a terrible idea anyway.
