[I moved this question to the digital piano section. Even though I'm more comfortable with the opinion of those who are coming from exactly my perspective already, only a few of you have the requisite knowledge regarding using a digital as a short term but complete stand-in for an acoustic, and besides, you guys have already helped me so much already! Thanks, and thanks again!]
