I've got an ETRS, with 75mm, 150mm, 40mm, two 120 backs, 135W back, and a prism finder (not metering).
What can I say? The camera is great, the lenses unsurpassed, and everything keeps on working. We did a comparison once with a friend and his new Nikon something-or-other with the latest, greatest 100mm lens. Kodak GOLD film from a souvenir shop, developed in main street lab, negatives examined with Leitz microscope: The 75mm MC had the best resolution by far; details were clearly visible which The Nikon lens didn't even hint might be there.
