[Koha] what barcode system to use

Dear all, We have decided upon ordering barcodes to mark our books. Do you have suggestions as to where the best deals can be found for custom barcodes as well as what system of barcodes to use? I found a supplier ("The Library Store") which offers code 39 codabar follett style "interleaved 2 of 5" mod-43 mod-10 as we don't have any previous barcodes to deal with, could you suggest me what works well (and more or less why?) thanks!
