Thanks for the replies guys. For me, a person who has not played a piano since I was very, very young, anything greater than 61 keys is far more than I need. I guess when you've been trained on a paino and spent many years playing with 88 keys, the need for additional keys is very real.
PSR-S950, TC Helicon Harmony-M, Digitech VR, Samson Q7, Sennheiser E855, Custom Console, and lots of other silly stuff!
