USB Barcode Scanners

Mike Hall posted about how easy it is to use WEPOS and a USB barcode scanner.  Which got me thinking about a project I have coming on the horizon.  I will be looking for a decent handheld barcode scanner(s) (maybe wireless), anyone recommend a good hand held scanner to work with WEPOS?  Or maybe integrates with .NET somehow?  Plug and Play?  I dont think I want a "wedge" type.
