I missed out on the 50-135's either outbid in the last 2 seconds or just didnt want to give that much. But probably a good thing. I think some were really easy to fix though.
Actually, I think some of them were returns from user error or incompatibilities of older bodies/firmwares. The 16-50 I got said 'AF not working' but I did the SDM trick and it came back to life. I still switched it to screwdrive anyways. If I ever sell it, I will explicitly state the history. I hope everyone is equally as honest and forthcoming and doesn't try to pull one over on their fellow Pentaxians.. well outside of the one lens I saw on here a week or two ago..
Btw the K-r body I bought on there in the Parts/Notworking did work but was a bit gritty around the mode dial and the shutter button randomly stuck. I cleaned it up and now it runs like a top. So handy spare body for dirt cheap. The only thing is the body has over 57,000 shutter actuations already. So it was well used. That is the other thing about buying a camera body in this bunch on ebay atm -- you REALLY don't know the history, so bid accordingly. The problem is if we end up with people reselling these and lying that they either don't know the history or bought it from a friend and then charging the normal going used price. That is just wrong. Please, people, don't do this to others.
I will also say there is someone on there that is bidding on just about ALL of the Parts/notworking Pentax gear. And I mean just about all of it over the past month (and has won a good deal of them). I wonder if someone is about to start a parts 'store' soon with all of these items broken down as parts? Be on the watch for that too. New replacement parts might not be new.
