Thanks gents.
George, I found some specs and a picture of that new KB you mentioned. I think you're talking about the YPG625. Thanks for the lead -- very interesting!
A couple of places are advertising it for $779 in June. It has a 5 band "master EQ" but I don't see any SM card slot, so off hand, I don't think it quite competes with the Privia 400R. (I see 400CSs around for $599, which is the 400R less the stand and pedal, I think.)
I appreciate all your comments very much.
You know, the quality of a sound clip depends soooo much more on the musicianship of the artist(s) than the sounds in the KB. I was listening to clips of the DGX505 and the P250 on Yamaha's site, and they put, oh maybe FIFTY TIMES more effort into the P250 clips!! Honest to dog I'm not sure there's much difference in the sounds on the two KBs. I heard some good sounds coming from the 505, but geez ... for one thing, nearly all the 505 songs dragged like my great, great grampa (who happens to be dead).
You don't spose this would have anything to do with the fact the P250 is almost four times the dough, do you? They wouldn't try to steer us toward the high priced spread, would they???

I'm going to a Guitar Center to try a PX-555R today.
Thanks again,
Rick
