Woolly Board anyone?

Does anyone know of a supplier in the UK of Woolly boards (or wooly board or jumper boards as they are also called). I would like to have one but haven't been able to find them anywhere in the UK. For those who don't know what I'm talking about, these are sweater blockers and look like this:

You either wash or damp down your knitting and then place it on this adjustable frame. Once on the frame, the jumper or cardigan can be pulled into shape and then it is left to dry. Dryer takes much less time than lying flat.
It appears they are pretty available in America and Canada but then, they do much more fairisle knitting in the round than UK knitters. If anyone knows of a source, please let me know.
