George.., come over to the dark side my friend Feel the want flowing within you... Never underestimate the power of the synth

Joking!, but seriously though..., the MO8 would be a great 88 key unit for you. You'll get mega voices, guitar arps that will--to put it nicely--greatly surpass those found on the PSR's.

You'll find that action on it far more enjoyable than the DGX, and YPG's. Plus it's still a Yamaha

I've always felt it was wise to have both. A decent arranger, and a good synth. Together they compliment eachother quite well.
