manufacturing date shows 2011:03:18 and shutter count 1230
That doesn't look good.
Off to the shop tomorrow.
Its normal for cameras to have several hundred shutter actuations on it when new. Was the 1230 figure after you had take some pictures or before? Pentax runs the cameras through several hundred test firings at the factory, before shipping. Its important that you are looking at the shutter count in the EXIF data, and not the filename (ie, IMGP1230.JPG).
The manufacture date is not definitive, either. It could just mean that it took eight months to get from the factory to the US distributor in Denver, to a regional jobber, to the camera store, to you. That seems a little long, but I don't think you can take it as proof that the camera was purchased and returned.
This subject comes up somewhat frequently. I don't think anyone has ever reported less than 200-300 shutter actuations on their new camera. 1230 is a little high, but not unprecedented.
