Bah! pastes - all you young whipper snappers want paste. Why, when I was a lad, we were given a brick, and felt lucky to have that! Even luckier if it missed our head when they were giving them out!!

I think the tip to contact Chris L is a good one - lots of happy people report good success and speedy delivery from that fine gentleman.
