We got our piano used for $800. It's an upright Whitney and this was nearly ten years ago.

my piano teacher was a lady who is our neighbor now, and it was $32 for once a week for an hour each month.

I stopped taking lessons before I finished the book series we worked out of-- I had stopped practicing and got burnt out I guess, but I can still play and play a lot now recently.

I wouldn't get a keyboard. *I* want one, but that's just because using my mom's laptop to record music and having to manually enter MIDI is so much trouble xD
