I thought it wouldn't break $20. The prices of lens certainly have gotten insane lately.
That's not too hard to fix. Was it the rubber focus grip model? When the problem is developing, the scale is coming unglued from the focus ring. It scrapes against the barrel, sounding and feeling like a horrible focus defect. Once it falls entirely off, the focus issue disappears.
What's odd is that you can find ten auctions a day for the Takumar 55mm. I have to force myself to avoid them, and still get sucked in a couple of times a year.
