WOW, very tempting. I've never had one of these, but several friends had them and loved them.
One friend had one take a dive and remain underwater for about 20 minutes in a fast flowing stream before we found it and retrieved it. Took it into a local, old camera repair guy who disassembled it, dried it, re-lubed it and re-assembled. Camera worked for many more years, good as new.
I've often thought of getting a K-1000, and this appears to be a very nice one. Will be trying to resist, I should be selling cameras, not buying more! Da** GAS!!!!
Someone hurry up and buy this.
