I don't think the K200D is water sealed. You need a K20D, or a K10D. the K200D is just the K10D in the old K100D body IIRC. What you get for the K20D though is just amazing.
As for batteries - I've taken 400 consecutive shots with SR turned on with some high powered MAHAS and I never ran out of juice ~ I ran out of memory card space first
And in all honesty...shoot RAW, not JPG
Yes it takes more memory, but the ability to do WB correction on the fly using any (free or not) raw editor, as well as grab some more highlight information is always welcome when post processing.
As for the high ISO quality - you have to know that Pentax and Sony both do it VERY differently...almost diametric opposites in that regard. Sony likes to crank up the NR a lot - the image doesn't have as much noise but it is more smeared and you lose detail. Pentax only sprinkles NR on its photo so the results capture more detail, but at the expense of more noise. I prefer less applied NR b/c I enjoy the details - if I want i can apply some NR on my own. Other people I know who are more casual and don't want to spend time dealing with that prefer an image with less noise even if it is more smeared. Go look at low light shots (iso1600 or higher) on both cameras and you'll see it pretty clearly!
