I own two, which I still use occasionally to make sure they don't gum up. It was the early 90s, eBay and internet photo forums were nowhere to be found, and all I knew about SLRs was that all the photo mags referred to the K1000 as the most popular beginners camera. So I got one when I went off to college.
It was my first SLR! I regret having given it away several years ago. I have actually been considering buying one just for nostalgic purposes, but it wouldn't be the same. I can't get my original one back because I gave it to an exgirlfriend who hates me. Passionaltly hates me.
