Sorry to see that Mike. Looks like an easy mistake to make and a lesson for us all as to how easily things can go wrong. Glad no-one was hurt - if you're going to have an accident a D3/4 is a pretty good thing to do it in.
Good luck with finding a D4. I'm sure you'll enjoy it. I found going from a D3 to a D4 a quantum leap in many ways, which I didn't expect.
Cheers,
Jon
