Yes, Bruce from AMD is a top bloke. I would have no hesitation in buying from Bruce/AMD again.
I would still have the Adelaide service fellow come out Damo, because if there is something shorting on the machine that is causing the board faults, the last thing you want to do is cook the next brand new board. Let the Adelaide company do everything from here since it wont cost u a cent and will be safer all round. Just my thoughts.
