OK, I'll fess up I will soon have the PA800 for the following reasons:

1. Vocal harmonizer: I need to incorporate into my act and felt this was the best chance to do material I'm currently not doing.
2. Acoustic piano: Looking for a different sound for a change.
3. Drums: More and more rooms are seeking the younger stuff and I feel this board will offer more opportunities.
4. Organs: I've always loved the Korg organs.
5. Songbook: Definitely interested in using this tool for live play.
6. Respected opinions of others on this forum who have raved about it.

All said, the S900 is an absolutely terrific board. If the 800 doesn't meet my expectations, I will immediately go to GC and grab another 900.
