Hi,

The differences between pa80 and pa60 are:

pa80: 4 outputs, vocal harmoniser option, flash card option, 2 x 22 watts, sampling function, user installable hard disk.

pa60: 2 outputs, no vocal harm, no flash card, 2 x 15 watts, no sampling, hard disk by korg more expensive.

Pa80: great keyboard but! after 2 years I have to admit that there is a structural problem in some styles (no natural fills, no natural pass from one variation to another). This is for me the only (but great) problem with pa80.

If you have no problem with a bad key feel, then probably the psr 2100 is the best choice.

Go and listen and good luck
