I didn't actually buy it, but my dad did, for me. Pentax K1000, November of 1979.
I needed it in a hurry because I was taking a photography class in H.S. and the ancient Minolta SR1 I was using jammed on a field trip and never operated again. Saturday rolled around, and Dad took me downtown to buy the Pentax. A rare gesture on his part; usually if I needed something expensive I was told to "put it on my Christmas list" and then come Christmas morning I'd receive a lesser and cheaper version of whatever I'd asked for.
I used that Pentax for a long time, and it still works. I've seen a LOT of K1000s with dead meters over the years, but mine escaped that demise.
