Originally posted by DennisH I was looking through my photos, and I realized that nearly all my favorites were taken with my K200 and 40mm Limited.
You might also check those favorites to see what ISO you used. As someone else mentioned, the K200 uses a CCD sensor and many people think CCD sensors have a better feel to their images when used at their base ISO, whereas CMOS sensors generally start to outperform CCDs as you raise the ISO. If most of your favorites were shot at or near your K200's base ISO, maybe that's part of what you're seeing, in which case you may want to go ahead and get another K200. However, if you're shooting at 400 or above, it must be the legendary Pentax pixie dust at work so you'd be smart to look for a used K5 or K30 so you can get the most out of your 15, 40, and 70 limiteds.
