Just purchased Corel Painter X. Version 11 is out now, so the price for 10 is dramatically less. I got my first copy of Painter when Fractal Design owned the software 91-95 and the packaging was an actual gallon paint can. (See below). The software has changed somewhat over the years but the core is basically the same.  It's by far the best software for achieving traditional fine art results.  A stylus tablet is must!
