My dad is looking to buy a new camera so he's been looking around a bit and asked me to do the same. I know absolutely nothing about them so was hoping you guys could help me out 
He wants a really good quality camera which will last for a long time. he's narrowed it down to the Nikon D200 and the Nikon D2x. I know the price difference is enormous between the two but if it's worth the money, he's willing to spend it.
personally I think he should go for the D200 because of the price since he's not into photography on a professional level and thats what the D2x looks like its for.
Your thoughts on the two models?
