Yes indeed, I can imagine prices making a temporary leap in the wake of this video, I'm happy enough to wait though as most things I've wanted have fallen into my lap just by virtue of keeping tabs on the local auction
I'd imagine there's an awful lot to go wrong with something like this so working examples must command a premium already so I'd certainly be after a "broken" set if I do get one. Fixing the stuff is half the fun though, right?
