Beakybird,
Generalmusic makes an 88key hammer weighted digital piano called the pRP7 digital piano. 50" long and 101/2" deep and weighs about 40 lbs. It has about 40 of the most popular digital piano sounds(acoustic pianos, electric pianos, clav, vibes, strings, guitar, jazz organ) and over 400 gm sounds which you access from a computer. It is 16 part multi timbre and has a pitch bend/modulation joy stick. It sells for $699.00. I think the studiologic 88 key controller is around $399.00 plus another $300.00 get you the Generalmusic keyboard. The sounds are very good and the feel of the piano is great.
