I utilize a sampler. Its Garritan Personal Orchestra's piano. Its not as realistic as I would like but sometimes its easier to use a sampler than find a player.

I imagine the best way to get a good crisp mic recording of a piano, would be to set up 2 mics , (for L, R stereo) near the piano's aural 'sweet spot'. The thing is, most piano's are different and therefore adjustments need to be made to take advantage of each piano's sound.
For a brighter piano, I tend to like a closer mic, to catch the vibrant key tones for a brighter, jumpier responsive sound. On an older piano, the wood has aged and probably has a different quality of sound. Therefore, mic-ing the piano a bit further might help to take advantage of the tone and pick up the natural reverb of the room/piano nicely.
It depends on what you want.
Jam it back in, in the dark.
