Offering a K20D

I have a K20D I'd be willing to trade for a used 540 flash or a Bower/Samyang 8mm or 10mm fisheye.
Before you jump on what may seem like a great deal, I must tell you the K20D needs repair. I suspect the sensor is loose or the SR is screwed up, because sometimes I get a sharp shot with it, but most of the time, pics are soft, and sometimes (especially with my 200mm at long distances) I can't find a sharp focus point anywhere in the scene.
Everything else works fine. Has a scratch on the LCD, which isn't visible when viewing pics. 32,800 shutter count, according to PhotoMe. Includes split-screen Katzeye that I installed about a year ago.
I just bought a K5 and have a K10D, and I don't feel like going through the trouble of sending it in for repair.
