Recommended repairman - Keith Leedham
If anyone is looking for a good UK based repairman I can wholly recommend Keith Leedham, factory trained Rollei man but repairs all cameras at very competitive prices. CLA'd my Rolleicord which had a dodgy shutter for 69 quid including postage where Newton Ellis had quoted me 80 pounds without post. Also very fast turnaround, aims to get your camera back with you within a week and achieved this with me.

Is a bit of a Luddite who may not reply to emails too promptly so the phone is probably your best bet.
