one thing the original poster might consider..the adorama 40d refirbs are 690.00 and a 3 yr mack warranty is about 39.00. pretty hard to pass up that bargin right now if your in the market for this type of camera. i agree with some of the other comments. if you really have not tested a 50d and a 40d side by side for your needs,,i would think it would be hard to make a valid comment. both are excellent cameras.
I'm in Australia so Adorama is no good to me by the time I import. That said, this deal offered a brand new 40D for the equivalent of $710 USD, so that is why I said it was a good deal.
Also, I didn't want this to turn into a brand war, or anything like that. As I mentioned in my OP, I already shoot with a 5D, a 1D Mark II N and a collection of Canon L lenses (primes and zooms). I also have a truckload of Elinchrom lighting equipment, both studio and location, so my purchasing decisions might differ from a hobbyist or enthusiast (how I envy some of you guys!
). While the D300 might be a great camera, I am too invested in the Canon system to start buying other brands, especially if its only a crop sensor camera. Not saying that it will never happen, but right now I have my Canon bases covered. 
In the end I chose the 50D over the 40D because, IMO, I was getting more long-term value. The extra resolution is welcome for studio shooting, will compliment my 5D nicely, and the 1D2N will keep plugging away at those action shots. See? Best of three worlds!
