I was ther too, and it was just few weeks ago.
You can see from my sig, which way I went
why?:
K200D
- controls much like K100D
- CCD as K10
- better in camera processing
- I'm fond of AA cells as they are easily replacable
K10D
- good size and good ergonomics, though I wouldn't mind grip being tad deeper (I have big palms with long fingers)
- 2 dials (programable usage of them is great)
- bigger, brighter VF
- don't mind not the best in camera processing, as I shoot RAW
- I could get it cheaper then K200 and it was brand new
good luck
