"Take a toy out of the original packaging and it can lose 90% of its value. wierd"
Seems a shame to me and I don't see the point in a toy you can't play with. I got a couple of steam engines (Mammod traction engine and Wilesco steam roller) a few years back and I read of collectors having them never used but the fun to me is that you can (even if only occasionally in my case) fire them up and see them working.
I got one of my brothers a toy for Christmas btw. Some Fishertechnik - this tractor kit. It's great stuff. Tim, who had a set or two back in the 70s, said it was a great "blast from the past", was reminded of how he enjoyed playing with it and that he had fun making the models this Christmas.
