Decent map editing techs?

Recently I've seen some quite good maps popping up, much better then the typical paint all nations painted a different colour stuff which is the norm.
Does anyone know of any place where it tells you how to do this shade in of areas to make better looking maps?
I have psp here, is it that or photoshop used?
Wish I could remember the name of who it was.

I can modify maps pretty good with MS Paint.

Me too, I 've seen some pretty good looking ones around though which couldn't have used paint with the way they are done.

In what way? If you know how, you can get some surprisingly good effects with MSPaint, like diagonal shading for disputed territory.
