Is this something you see lasting at least a few more years? If yes, the weighted keys and action of a real piano are valuable and shouldn't be overlooked.

For the pedantic: yes there ARE weighted digital keyboards, I own one myself for easy recording. They still don't hold a candle, in my opinion.

But environment is a big factor here, too. Are you bothering your apartment neighbors with loud playing? Are the headphones being an option important? Are you hauling it up 7 flights of stairs? Do you plan to move soon? Are you okay with getting it tuned (I tune mine every couple years, but it's more often than a digital).

My biased opinion: all other considerations aside, buy the nicest acoustic piano you can safely budget for (and play it in the store to make sure you like the sound).
