Iv'e have all my lenses , Calibrated and Element Aligned by a technician . It's a must.
In fact now I don't even take them out of the box when I buy them. The problem is you might be correcting for a back focus issue when you really have a Element Alignment problem.
I would talk to your Large News Paper in your area. Normally They have all there lenses calibrated and probably know of a good technician . Or If you live in Canada private message me and I have some one I can recommend.

P.S. Don't bargin shop for this it is Painstaking delicate work.
If you are sure the lenses are the problem, then you will have to get the camera and lenses serviced.
I may just buy a lens align, is it much better than http://focustestchart.com/chart.html
As Howie has said, the equipment is built to tolerance ranges, so while there is some variation in people's equipment, it should not be so much to cause problems.
Naftoli, if you really want to buy a LensAlign to deal with your issue, I have a Lens Align Mk I version I could sell you, if you are in the U.S. I bought it when it first came out and ended up not using it, because like I said above, I haven't any need to use the micro adjustment feature.
set my camera on a tripod tethered to LR. ISO 200,lens wide open,shutter speed 1/200,on camera manual flash.
Ive been using "Tims auto focus chart" i now have my camera set to -13 for 70-200 f 2.8, -11 for 24-120 f4, -8 for 50 1.8, etc.
The first hour i spent i was changing the default micro adjustment setting for the whole camera but i wasnt seeing any difference btw diff settings, i then tried putiing it at -20 and then +20 and there was virtually no difference btwn the two, i then started using the calibration profiles for each specific lens and then i started seeing a difference
