Sad to hear this. Don't give up, though. There are still good deals on ETR models out there. I like Bronica's 645 format the best because it is the most system-like of all the 645 SLRs made, with the possible exception of the Contax, which still comes at hefty price.
I bought my ETRSi outfit at what I suspect was the nadir of medium format camera prices. An eBay auction, of all things. I won a small outfit, which included an ETRSi body, prism finder, 75mm lens, and a 120 and 220 back for $127. !!! I was surprised that I didn't get outbid. I check on prices for the ETR models from time to time on eBay, and I find that there are still excellent prices to be found. I have since added a Speed Grip E (essential accessory), 40mm and 150mm lenses, plus a couple more 120 backs, and an AE-II metered prism. I now have a top-notch, killer 645 outfit, which was rather painless to put together. So far, my most expensive item has been the 40mm lens. I would like to upgrade to the AE-III metered prism someday, but they are relatively pricey compared to the rest of my ETR gear.
