MCM has them on ebay at reasonable prices in lots of 5. I bought 2 lots which is a tube for AU$650 posted. They are still available.
I mustn't be looking properly as I can't find it on ebay at the price mentioned above. Could you please post the link. Cheers.

I have two encapsulated Planks that I am prepared to sell. No rolls I am afraid and they do have a high premium. PM if anyone is interested...
