Hi, just wanted to ask you a few questions about the 630. I saw your price and that is what concerns me. I have a PSR540 which is of the newer PSR series. What is the difference between the 540 and the 630 that really sets them apart. I didn't pay anything near $750.00 for mine and I bought it brand new with the adapter, pedal and headphones. The 540 has MANY of the same features as the 630, plus the sound quality is a little better. Not trying to knock the 630 because it is a good keyboard. The price you're asking seems a little high considering the board is no longer in production and they have done so much more with the PSR 540,640 and 740. Any help would really be appreciated...

Thanks,
Squeak
