Not sure I'd describe £7k as particularly cheap, but perhaps I'm a bit out of touch.

The rate these things seem to be going up in price makes me wish I'd bought a couple a few years ago and locked them away. Guess that's what happens when so many have been broken in recent years though.

As said though, got to be worth a look, and if he doesn't like you poking it, flash the cash in his face, and then walk away laughing at him for what he's missed out on!
