I don't quite get this, you are prepared to pay £79.50/1000 for inferior targets when they can be purchased from the NSRA for £46.26/1000 or from Kreuger for £30.00/1000. They may be single sided, but you can only use them once anyway. The NSRA will sell you as few as you want, you do not have to buy 3000.
