Mr Worry, having been to the shop itself, I'd warn against buying anything at all from there. It's a little photographic aladdin's cave, but the proprietors are not the most agreeable of people. Nothing is priced and they rely on their own Amateur Photographer adverts to determine prices. When I turned up, they were apparently in the process of cataloging their stock. Why not check out their website, last updated July 2006.
If I were you I'd check out www.ffordes.com or www.mifsuds.com. Nicholas didn't make me feel welcomed.
