My K20D is one great camera, just that there is that "little something" missing, as I explained in my opening post. As for the K7, it is now being used with my "other glass": 31mmLtd, Carl-Zeiss 85/4, and a Tamron 70-200/2.8, the latter when the lighting conditions are perfect.
Yeah, the D7 seems like a great piece, but I haven't read much about it except that it performs very well. Expensive too, right?

There would be pros and cons to a move like this. A month ago, i spent 2 1/2 hours shooting stills during a dress rehearsal of Chekhov play, about 15 feet from a guy shooting a D300s. Then I was given all the photos to select the 16 for the lobby. I picked more of his to post than mine :-), but that was primarily due to a better choice of ISO (he chose 3200 ISO while i chose 2200 - his afforded greater DOF and shutter speed) for some darker scenes, and also he was in tighter on framing.
In comparing RAW images, I don't see any marked improvement in noise from the D300s to my K20D. (Edit-I'm comparing my k20 pics at 1/2 step better ISO, e.g. 2200, to the D300s at 3200 so thats a potential 1/2 step improvement, but still its not the 1+ step Kx improvement)
This is all by way of saying that the Kx sensor is a harbinger of a step change in ISO performance in newer sensors. The D300 and K20 sensors are from an early 2008 performance level.
I read a related article in last month's Outdoor Photography magazine that said newer higher camera ISO performance was helping nature pros carry lighter weight f4 lens rather than heavier more expensive f2.8 glass. Not only carry, but the cheaper glass was allowing some to buy rather than rent lenses. (and of course, some of this remarkable ISO performance was from going to a FF cameras such as the Nikon D3)
I believe you would get better AF with your hypothetical D300, but would you lose out in not having a model with the improved sensor ISO performance in newer entry, enthusiast and pro models that are coming into the market place. As a guy who does occasional live theatre work, my top priority in any new camera is ISO performance. And frankly, i don't care whether you buy P, C or N :-)
