Barcode cradle for iPHONE/iPOD touch

Hi all,

Few months back I found a website which sold hardware barcode scanners for iPHONES/iPOD touch. Now I know you can buy the POS units but I'm really just after the barcode scanner.

I also understand that this can be done via the camera but it isn't very practical for warehouse use.

Any ideas comments would be great.

Thanks
