And you'll see many articles about using your dslr and a macro lens to make slide copies as Bojan suggested. For copying slides it's pretty good. As Bojan pointed out negs are more difficult. If you can get hold of a negative of a grey card or an colour standard negative or shoot one yourself, you should be able to find the colour balance a bit more easily.
A modern DSLR with 14eV dynamic range has a bigger dynamic range than a Dmax 4.0 scanner. And with one shot instantaneous capture it's much faster than three pass scanning.
If you really want a scanner, the EPSON Perfection V800 is very good.

The Plustek's are a decent scanner and a bit cheaper if your looking for value for money, the Epson is a better product though more expensive.
The Nikon SUPER COOLSCAN 4000 ED (LS-4000 ED) was the best consumer scanner I've used, but they are discontinued. If you get one second hand, you need to buy 3rd party software like VUESCAN software or Silverfast to run it. When they discontinued, Nikon stopped updating the drivers as operating systems changed.
