I don't know whether GS or Lee Andrews collimated my 12in but it was in great collimation after a 1500km roadtrip to be delivered to me.
While I am not even close to an expert in collimation, I found it quite easy to collimate well enough to get diffraction spikes with no tools at all - not even the film canister (now I have gone digital I don't have any loafing around any more)
Luckily the secondary was fine and it was just a minor adjustment of the primary - heaps easy using the defocus and centering the shadow method.
