Thanks for your input, Bob, it's nice to get some knowledgeable feedback which supports my choice. Unfortunately, I'll be inScotland for the next meeting but may try to get a personal lesson from you sometime.
Thank you Martin, that explains all. Still not sure of the relevance, though, but I am probably not knowledgeable enough on the subject to recognise the difference between shoddy toys and the 'right stuff'. Or am I just being patronised, in the nicest possible way. No offence taken!
Terry.
