I got a D1x with buffer upgrade some years ago when my D2Hs was stolen and I did not have a lot of spare cash to replace it. I needed high ISO capability for indoor sports. Doing a little research, I concluded that the D1x shooting raw with manual WB was the best alternative for well under $500 at the time. This was the pre-D700 era.
A little later, I considered replacing mine with a D2x that a friend offered me for a reasonable price. Tried both for a week or so, but kept the D1x! (remember the need for high ISO) Later, as technology (and my finances) improved, I replaced the D1x with a D90, and now FX. Still have the D1x as I kept it for a backup.
The D1x was an underrated camera, IMO. I liked the D1x raw files better than D200 files. The poor auto white balance and battery did make using the D1x more of a chore to use than the next generation of cameras, but I don't think the subsequent generation really improved image quality. Different story when the D3/D300 became available, though.
