Anyone know where i can buy some 3" (or whatever size they are) in the uk for a REASONABLE price (i dont mean £10 each) i dont want to be buying a huge number, just a few to play with.

I'm asking this here as i'm sure many of you will have looked into buying this size disk in past hope of the cube being cracked and could therefore point me in the right direction, i know they are made by sony (for their dvdr cameras) but does any of the cheaper manufacturers deal with them at all?

i need dvd-r not dvd+r discs
