so i've been reading a lot about these two cameras, and have found that they are both pretty similar to each other as far as their internals go. now i'm sure not everything is the same though obviously, but what is so different that justifies the close to 500 dollar price difference? i know the d80's censor is a tuned down version of the 200's, and that the d80 can't shoot as much frames per second as the d200 but that doesn't bother me. the only thing negative i've found about the d80 is that its meter is a bit off at times. what i'm really asking is the d200 worth 500 dollars more than the d80? any input would be appreciated.
