For those who care, since the K1000 has been mentioned, and since that was my main shooting camera from the 1980s to the early 2000s, curiosity got to me and I checked current prices.
KEH is selling the bodies for $189.82 in excellent shape, which is almost as much as I paid for mine with the stock f/2 lens back in the days. They also have "bargain" ones for $129 and "ugly" ones for $69.
Checking That Auction Site, prices are all over the place with "mint refurbished" ones with the f/2 lens going for $159 and others that look like they are in decent shape, many with what I would call grab bag lenses, going anywhere from $70-ish to $180-ish,
Nobody seems to qualify if they are the older Japanese all-metal ones or the newer ones with the plastic parts. Mine is the older all-metal ones and I can feel the difference when picking up the partly-plastic ones.
