Not everyone's cup of tea, but here goes...I've got series 6,7,8 and 9 available if anyone's interested, bought them new and only watched once each and no scratches whatsoever. Will send in the original boxes, minus the original plastic, of course... Series 8 is the American release, so will need a multi-zone DVD player, but the rest are official Australian releases. They retail for $69.95 from K-mart, looking for as close to $40 per set including postage, but will drop price a little if neccessary. LMK if any interest.
