I have a SRT101 that Greg Stelz just went completely over (he strips it completely down) and he is right, it is amazing how bright and clean the viewfinder becomes after a complete thorough cleaning. And he fires the camera for a couple of weeks after oiling the springs, to let the oil really sink in. And calibrates the shutter several times, including right before shipment. I am really impressed with his work, and have several other bodies that could use a complete overhaul at his spa. And he calibrated the meter to run on 357 watch batteries, and it is now -dead-on- with my most accurate handheld meters.
