Just picked up a Pentax K-x with 18 - 55 and 50 - 200mm lenses. (When I say "just" I mean last night)
What led me in that direction were some of the attributes of the camera that made it a little more than an entry-level system while still having the "beginner" prompts available. It will also fit all legacy Pentax lenses, which I have a few of.
I liked the idea of using AA batteries of whatever composition. Currently utilizing AA Lithiums, but the camera will work with rechargeables or even alkalines in a pinch.
Image stabilization is built into the camera body and seems to work well even at higher zoom levels. Since it is a 12 mps camera, the highest quality images are fairly large (5 Mb) so they will eat up some disc space, but 2Gig and 4Gig (SD and SDHC respectively) cards still have plenty of storage. I have not made a choice on or worked with editing software as of yet to see what I can do from there. Rapid fire at 4.7 fps really catches action sequences well.
I am going to continue to experiment as I knock the dust off of the old "photo-lab" notebook.
