back in the day I had one of these and a D70s.
The D100 nef files were better than the d70 at 200iso, but the jpegs were hopeless. The D70 was a little better at 400iso and both were hopeless above 800.
My D100 was starting to get a fuck ton of hot pixels before it took a bump and died. The sensors did degrade on them but if you want that great CCD colour, go with a D200 or Fuji S5 pro. you can probably find them for cheap.
