I have used a Metrologic keywedge scanner like we use on Passports with no problems. Cheaper too.

What he said.
Use the same model that the Passports use, it plugs inline with the PS2 keyboard. There is only one or two configuration codes you need to scan (basically whether to expand short barcodes automatically or not) and you're off and running.
