Thanks all. Plenty to think about. Definitely going to have to visit these places. One is right near my Sons place in Chelmsford so I'll try them first. No rush, as long as I've got them for Christmas as Mrs Mottie will be buying them for my Christmas present. Only stipulation from her is that they don't end up in the loft next to the fishing gear, the golfing gear, the toy robot, the motorcycling helmets, the chemistry set, the telescope......
