The K100D is an excellent camera, easier to operate than the K10D, thanks to its picture modes (landscape, portrait, sport, ...) before starting the Sv, Av, ... and the full manual mode.
I used to have an *ist DL, which was the release before the K100D, and I learned everything, since it was my first dSLR.
Two other advantages of the K100D over the K10D : the use of standard batteries (count USD 50 a pop for the K10D) and the very sensitive sensor (same surface as K10D's but 6M pixels, so each pixel receives more light).
Now, the biggest part is to wait till X-mas
