D'oh!
Just a warning - I will not name names as I don't need any email attacks.
I purchased a "freshly CLA'd" Zeiss Sonnar (50mm f/1.5) that, on closer inspection, is in terrible condition. It looked fine on the outside, but the aperture ring had play in it and the blades were stiff. So I sent it off to a trusted repair man. It turned out that the center element has separation and may have been treated with oil. The oil can't be removed, and the lens will probably fail when it heats up and the oil expands. The lens also had been relubed with Vasoline! And, on reassembly, everything was put together finger tight only.
The lens has now been properly serviced and I'll use it until the elements completely separate. And I'll watch for a donor lens with a good center element.
Just an alert - make sure you know what you are getting when you pay for a CLA.
