It came from Transair's London outlet - it was a Xmas present that cost £60 (!)
Yes, it is a bit expensive, but it looks very durable and sturdy. It's a US manufacturer, and is designed to specifically fit the yoke of Piper Aircraft. Hence, it sits very well in between the yoke handles, and doesn't impinge on the travel of the control column, and neither does it prevent full movement of same.
All I'm going to stick on it is maps and approach plates - I don't have a flying suit with kneeboards, and I find strappable kneeboards cumbersome and maybe dangerous - I recall recently that a student heli pilot damaged his aircraft when his kneeboard came loose and restricted the controls. Can't find a link - will post if I find one.
Thanks for the input - I asked the flying school I'm with and they said it was fine.
Flyin'Dutch - did see the £10 one, but it seemed a bit flimsy (looked like a bulldog clip on a stick) so decided to ask Father Christmas for the shiny other one
