- SuccessfulMattatuck UU Society Keyboard$1,550 RaisedGOAL $1,500 The Mattatuck UU Society (Connecticut) is moving. Our upright piano is not worth keeping. We are buying an electric piano/keyboard. We have a small but growing congregation and music ministry. The keyboard costs less to buy and maintain, is easier to move, has a variety of tones, is easier to record with, and can be used outside.
