I bought an OM-10 new when they first came out in, I think, 1978. I still have it and as far as I know it still works although I haven't used it for years. When I was using it heavily it never put a foot wrong and repeatedly delivered well exposed slides with the help of a manual adaptor. Given all the bad-mouthing of the OM-10 on the web it's nice to read a positive resumé of what was at the time probably the best of the "budget" auto SLRs. It was the best-selling SLR in the UK for several years I think. My only complaint is that the price just about halved within a year of my purchase - perhaps later ones were not as well built in order to get the price down. I've stuck with the OM system ever since and never regretted it.
