I have upgraded twice since my *istD although I still use it regularly, hot pixels and all.
I went to the K10D because I wanted SR and a higher MP body.
I have since upgraded to the K7, put a split image in the K10 as a MF body but the *istD is still chapms for flash photography with my collection of K mount lenses.
the hot pixels have increased over time, but for general shooting they don't bother me, and if I want to print something it is still easy to edit them out.
If you have manual aperture lenses, the K7 would be better as it seems to meter better than K10/K20.
This is all assuming you want dual thumbwheels.
Also, if you are using high ISO, K20 or K7 would be better as the CMOS sensor performs better than the CCD of the K10
