Thanks for all the advice. My main reason for wanting to get a new camera is that I want something fast enough to keep up with the little one who is due in Feb, and can help me make a little more of what my wife claims is a "not great, but pretty good, definitely better than me" eye for what will make a nice shot.
I don't plan on taking much, if any, wildlife. Action shots that I've seen with the K100 aren't too bad. I'll take more traditional team sports, not motorsports - so people are moving 5mph, not 180mph.
I had planned on a K100 kit plus the 50-200 lens as my starter set, and looking for a nice long screwmount tele at either 300 or 400mm. Coupled with the 50/1.7 that my sister-in-law is giving me, I expected to have a nice starter set.
The benefit that appealed to me the most was the CCD cleaning system. Other than that, there wasn't much in the K10 that I thought I "needed". But, I guess a Rocket blower thing should be cheap and good enough...
