I checked out the PSR2100 again at Walter's Music and they just got in a PSR3000. So I did a head to head on both boards. The PSR3000 blows away the PSR2100. Unfortunately they didn't have a PSR1500, so could not compare the PSR1500 to the PSR2100, but it seems to me that the PSR1500 sounds better from memory. Unless the EQ was adjusted poorly on the PSR2100. If you make an adjustment to the EQ and then turn the keboard off then on, will the EQ not revert back to factory settings?
The salesman then informed me that the store has a 6 month no payments, no interest feature. Visions of PSR3K in my head.
