In fact most of the posts suggesting it have pointed to the drawbacks. Of the methods suggested, the TV trick (for faster speeds) and the phonograph method for slower speeds are perhaps the easiest in that they don't require special equipment or techniques. However, I think there's a need to find something better than a record player, as these are rapidly becoming "special equipment" :-) Steve
