Sorry guys, feel terrible now but I put a bid in at the last second that I didn't think would win and ended up getting lucky. I didn't realise the listing had been discussed on this thread - I've had a saved search for a White Water for ages and was watching it since it was listed.
@jonathan - Will offer you first refusal if I move it on as I've now read back and can see you were first to say you were bidding on it. Strangely enough I only regret selling two machines, WH2O and TNA. Both great games.
@s000m - Will offer you second refusal if Jonathan passes!
