I have a Nikon FE getting a CLA and repair from www.camerarepairs.com
in Avon Indiana (Central Indiana)
I do live in the next town over, and Bob (the owner) has been in business since the 70's.
He has cleaned a repaired many lenses and cameras over the years for me, and I have never had a return for a bad CLA or repair.
I just aquired a Nikon F2, and I plan on getting a CLA by Bob also done. His charge w/o a major repair is around $75 with a 60 day warranty.
If you are a user, than an under $100 CLA is worth it.
