Thanks mabuge. Yes it was me. Since I wrote above I got frustrated as the LensAlign delivered to the UK was $64 for postage! Michael Tapes has answered me in that they have introduced rate of $16 delivery and if I go the website the new delivery cost will be reflected. I did and it wasn't, still $64! Michael has said that if I checkout then write an email to them the lower postage cost will apply. Too messy for me, but I will have another look soon just out of curiosity.
Anyway, I think I am being persuaded by the article, excellent as it is, to go looking for trouble as I've always shied away from AF-fine tune after using a LensCal once and it told me nothing. Yep I think it's a waste of money too. No different to the free printed out pdf test sheet and set the camera to 45 degrees.
I may buy a lensalign when I hit trouble, but for now I'm awaiting the return of my 70-200mm from the repairers.
