I was fortunate enough to be given a complete set, minus the final copy which the previous owner loaned someone but never got it back, about five years ago now. I've been on the lookout for that final copy for a decent price but no luck quite yet.
It is interesting what people say about pictures. Personally I've always learned more by looking at an image and taking in what that tells you. For example, what insignia is a vehicle carrying, what is in the background etc. I suppose it shows that everyone is different.
I liked the Dinky Toy analogy mentioned earlier in this thread in relation to the price of a mint set of W&T.
