It seems like a waste to throw away 15 years of piano lessons--can anyone recommend an electronic replacement for an upright piano? Space isn't too much of a constraint (I have an empty guest room I can set it up, obviously it would be smaller than the upright it's replacing), and there seems to be a pretty wide array of prices. What I'm not sure is how close these relate to quality. In particular, I'd like to get it on Amazon.com if possible, since I have Amazon Prime and the shipping costs would be pretty steep for a large electric keyboard.
Since I live in an apartment, my primary method of using it would be listening through a pair of $70 large earphones.
