I would PM graeme and get loads of photos sent to look at, at the price he wants for it you will always get your money back. I have been out with graeme and the boat looked pretty good to me, haven't seen his current engine though, it had a non PTT engine before.
i understand your concerns about buying blind though, but buying off here can be slightly less blind than ebay for example!
Like someone suggested use another ribnetter as a middle man. not me though cos i am not entirely impartial as i know graeme.
at the end of the day £2K aint that much and you wont get a much better one for that money.
