I highly recommend the Alesis Qs8.2 or the Qs8.1. It is a 88 key fully weighted synth with expansion card capability. They have a Fantastic Grand Piano expansion card with unbelieivable Stereo Piano's and Rhodes sounds. The action on the keyboard is very close to a real keyboard. And when you are bored with the Piano sounds, you can play around with it's Synth, sequence, and arpegiator capabilities.

I purchased my Qs8.1 for 850.00 from Sam Ash.
