This is not to dig on any of the other well-known Rollei service facilities, but to offer an alternative, as the well-known guys are often VERY busy and backed-up. I took my Rolleiflex 2.8E1 in to ProPhoto on I Street in downtown Washington DC. They gave it a thorough CLA, adjusted the shutter speeds back to tolerance, and re-aligned the lens panel which had taken a bump in the past and gotten out of whack. They had it back to me in three weeks. It was a little less than $450, which although a little expensive, was well within reason considering I had my camera back in my hands in good working order in three weeks, not three to four months. If you're in the area, they're worth checking out.
