[Koha] Source and pricing of barcode scanners in .nz

Hi all My partner teaches at a small school in Hamilton, New Zealand, and we (me being the resident geek) are looking at Koha on Debian Linux for their library. We need to do a full costing for this exercise, and the only thing I don't have a ready source for is the barcode scanner part. Does anyone on the list have information on sources and pricing of barcode scanners in New Zealand? I've looked at *my* usual shopping haunts, but I guess barcode scanners aren't the sort of toy geeks usually like to play with ;) Many thanks Regards Richard
