I've had almost all my cameras CLA'd in the last two years and they are all like new now, and should be good for another twenty five years, although I don't think I will.
Actually, Camerarepairs are Mike Spencer and he is a one man band. I've just had a new (to me) OM2n come back from him. I've had 3 OMs refoamd and CLAd by Mike now and he is highly recommended. At the price he charges I wouldn't take a discount even if one was offered. If you are UK/Europe based he should certainly be high on the list if you need an OM sorting. His CLA on OM1s BTW, includes adding a diode to the internal battery circuit to use SR44 cells.
