Yes, you are paying more for it but you are also getting better build quality and a lot of other features that the 40D doesn't have. I'd gladly pay the price tag for the D300 with the battery grip and not even think twice about it. It's a very stable camera and Nikon currently has a better offering in the prosumer range right now even though it is expensive.
The 40D feels more flimsy in my hands compared to the D300 but I won't deny that the 40D is a great camera. The D300 is an overall better camera, even if not by an incredibly huge margin.
It definitely is the better of the two cameras, but the features you get are again dependent on your budget and your needs. For some, the $1800 price point for the body alone may well be worth it if you require them. For others though, not so much.
As a hobbyist, I'm pretty satisfied with the output of images I get. (as will most others using any modern DSLR; as is Brandon with his 40D--was it necessary to bring up a competing body?)
For me? I personally am waiting to go FF in the next few years and will be watching the market to see how it fares. Still waiting on a competitor from Nikon for the Canon 5D atm.

What's the final word though? It's the images that you get out of the cameras and you can't deny that they're both marvelous. I'm pretty confident that if a random pool of images were chosen from select professional photographers using the 40D and D300, you'd be hard pressed to notice a difference or identify which is which. Let me take out a quote from you in another thread:

I'd rather not stand around and talk like I know what I am doing. I will let my pictures do the talking. As I said before, I have taken better pictures with a point and shoot camera than what some people can take with their expensive DSLRs. It takes a lot more than fancy equipment or an education in order for someone to be great at photography. It reminds me of this guy I know who has 2 bachelor degrees and talks so highly of himself and his achievements, yet he bags groceries for a living because he doesn't know how to apply himself or his education correctly. Talk is cheap.
Amen.
