I would like to echo what everybody else has already said. Get well soon Chris and "good on yer" Andy for taking up the challenge.
Knowing the passion and quality that abounds at Saturn I think this is the best possible outcome in the circumstances.
It's a shame Chris could not complete it due to his unforeseen circumstances but I am 100% certain that Andy will do him proud. I look forward to buying the book, I may even be tempted to build one. Don't tell the Missus though
I enjoyed my other build immensely, even though I did not see it through the registration process.
I wish you all the very best with it, the project is in very safe hands.
Dave.
