This whole conversation doesn't even make sense...comparing an $1800 D200 with a $7000 1D. Can someone grab a reality check. If anything the comparison should be between a D2X and a 1D, and even then its a stretch. Fine, Canon makes a great camera, but so does Nikon.
Fundamentally, each person needs to find the camera that works for them. For instance, I'm a novice photography just getting started. Will I notice the differences between a Nikon D50 and a D70s? Probably not. Now, does that mean anything to a more seasoned photographer? Not really. Someone of a greater skill will notice subtle differences between cameras and lenses.
The bottom line is that such extreme claims and debate about cameras that don't even compare is a waste of time relative to the original question of what options there are in the $2500 range. The 1D is definitely not even in the ballpark. The D200 is a definite consideration as are the various Canon cameras. I've got a brother-in-law who just purchased a D200 and the samples he sent me are simply amazing. That said, I can't afford a D200, but have friends who use the Nikon D50 and are very happy with their purchase. Thus, the discussion about D50's is on target for ME.
Thus, how about some of you experts out there take a breath and speak on topic so the rest of us can learn and not just waste our time reading about two people's strong opinions about cameras that don't even compare to one another. Canon makes great cameras and Nikon makes great cameras as do Minolta and Pentax.
Now that we've got that settled what are some things to keep in mind as ejlatstl looks for a way to blow $2500? I don't have $2500 to blow, but the conversation, as long as it is relavant, is good use of my time and I'm sure some others'.
