Honest question - what is it about this camera that is attracting you all?
Surely a gripped up d300s, is a more capable crop body technically speaking... so what's the attraction? collectors? nostalgia? Just trying to understand it all..
A gripped D300/300s is a good camera, no doubt, but it lacks the solidity of a body like the D2 where the grip is built into the chassis. Plus, a grip on a D300 extends the height of the body by what doesn't look like much, but it makes a whole world of difference when it comes to handling (it's probably a centimetre); I moved from a gripped D200 to a D2x and immediately, i found the handling improved - the vertical grip on a D2x is more contoured and your fingers sit around it much better.
In terms of imaging then the D300 is better at high ISOs, simply because it can go higher. It also has CLS built-in, which is handy for some people.
However, for me anyway, the built and sealing was one of the major factors in deciding to move to what was, at the time, and older camera. Me and AWP have both said regularly that a D2x with a better sensor would be great and its only high ISO that leaves me thinking about moving to something like a D3. However, the crop factor is a big part of what makes this camera still very relevant - there's nothing else like it available from any other brand. Yep, you can get a 1D with that 1.3x crop, but it's not the same (although I can see the point in 1.3x as a FF/crop crossover) - I always said that long glass was a much bigger investment and having DX means I get more bang for my buck with long zooms. It's much easier (and cheaper) to get a UWA for crop - my 14mm f/2.8 was a mere £250 - but to go a bit longer than say, my 70-200mm, I'd be spending a hell of a lot more (£1000 for a 300mm f/4) unless I went down the TC route, and then that has its own pitfalls.
If I was to sum-up, in terms of tech, here's how I see it in terms of how it suits me (although I'm trying to be very general):
PROS
*Build quality is the best - essential for the abuse my cameras get
*Weatherproofing allows me to work confidently outdoors in all weathers
*Easy menu system - perfect for shooting in a hurry
*Massive (2000+ shots) battery life for a mere £100 - means I NEVER have to change during a shoot
*Handling is better than a gripped body and suits my hands
*Utilitarian design that fuses mechanical with software-based controls; main controls are easy to sue with gloves
*Nothing fancy like scene modes - just basic Av, Tv, P and M
*Controls are intuitive for on-the-fly shooting particularly the rear (thumb) command dial
*Weight helps balance out longer lenses for slow shutter speeds
*Ability to use variety of Nikon lenses (not just AF-S)
*CF card compatible - I prefer them to smaller cards
*AF speed is excellent - 11-points are very easy to use and well spread across frame
*Cheap as a used buy (gets you 'pro' credentials without spending a fortune

)
CONS
*CLS isn't built-in, which may be a problem for some
*Technology is six years old
*One size - can't remove the grip if you fancy a lightweight shooter
*No AF fine-tune option
*'Only' 11-point AF
*No video function
*No liveview function
*No dual memory card slot like D300s
Of course, many of the pros can be seen in other, newer models like the D300s - these are just points that I saw as a bonus to the fantastic build and handling. The cons.... well, I have to live with them until I can afford a D3
There is also something nice about this body that's hard to put your finger on. Maybe it is nostalgia.... actually, it probably is - the though of using 'retro' gear professionally does bring me a good feeling, although I know that's probably seen as a bit of a wierd, unprofessional viewpoint. I wanted one of these since I saw one some six years ago and although technology has moved in massively since its introduction, for my shooting, I've found there's very little that I can't do with this body when I attach the glass and flash units I've bought.
And the colours are pretty good too....
And ISO 100 is awesome....
