The D300 basically replaced the D2hs AND the D2x, for all but special circumstances. There are a lot of advantages shooting the pro body design. I like being able to quickly do a white balance, etc., by just pushing buttons on the back of the camera, etc.. The D2hs was also the fastest raw shooting Nikon until recently when the D3s hit market. It can shoot fast, and long before starting to stutter.?
AF accuracy on the D2H and D2HS, both of which I used, had its own quirks.
More serious was the LBCAST sensor, which, while I loved the color saturation, had quite narrow dynamic range and behaved very strangely due to IR interference with black nylon or with any subject with slightly dodgy skin (e.g. veiny facial skin that therefore gets us back to that IR problem again, or someone profusely overheated from exercise).
As far as I am concerned the D300 almost completely replaces the D2HS. Better AF overall, a bigger viewfinder image (comfortably the biggest of any APS-C/DX crop sensor body), less noise, more dynamic range, more usable resolution even at high ISO, and very nearly as much speed.
So if you shoot a lot of raw, fast, and looooong.. then the D2hs might be a better buy over the D300- but only if you do that, OR if you need a camera to shoot exclusively for web blogs/online news.. and in that case, I'd rather shoot the D2hs hands down.
.. for everthing else, the D300 is a better camera AND a better buy.
I love shooting the D2hs, but there comes a time when you just have to buy (and use) what makes the best sense for your intended use.
I generally would not recommend bothering with the older camera bodies, and instead would recommend getting a D300 at the least.
I have to say this though.. I don' know how much the D2hs is worth today, but you'll be able to make a buck with it- can still produce more than its monetary worth on nearly every shoot, so in that respect its still viable.. but... so much easier using a newer body, newer technology, and better high iso performance
