Thanks for the link, but I've already taken the plunge.
I was on the case last week as I need to get one sorted, the New Holland sold, every JCB I enquired about had just sold... so I got in the truck and drove to Barnes Plant on Monday to see 2-3 he had in stock - two of which were still there but sold - however I had predominantly gone to see the Project 12.... which I bought.
It was over budget, but is pretty clean for a 22yr old machine - cab is almost spotless. Two owners from new. It's still to be delivered, but I think I bought right.
