I have four GC stores near me and yesterday I went into one of them further from my home. Unbelieveably, they had a pretty good selection of arrangers, including a PA800, s900 and s700 stacked on one stand. I've never seen or played any of these (bought my s900 sight unseen). So I sat down to the 800 and played a couple tunes. First impression - keys are short and light - yuk! Next, the few styles I sampled sounded very good; liked the drums a lot. I would put the style composition somewhere between the Roland and Yamaha, maybe a bit more similar to Roland. I had a problem switching out of the EPiano so I never heard the Kord Grand, but I did play the s900 grand piano above it and my friend next to me said - WOW!
So, in the brief 15 minutes I spent with the PA800 I can't say that I didn't like it, but I sure am happy I saved the money and went with the s900... for now.
ps- I'm still having problems adjusting the s900 vocal harmony. It still sounds terrible to me. I'm either going to use my Harmony M or just go straight into the Compact with no harmonies (my voice is so beautiful, I don't need harmony - ahem, ahem,
