Barcode scanners Metrologic Scanglove IS4220 PS/2 interface Still have them laying around. $14 shipped p4 3ghz/533 $20 shipped. I think the motherboard went flaky but i think the chip is ok.

It looks like a lot of Laser scanners are out the door already and they'd rather sell you the more expensive optical ones. I have a Wasp barcode scanner, pictured below, that I use at work.
