Marc,
If you wan't to see how these 2(and other similar) keyboards compare feature/function wise
http://www.netzmarkt.de/thomann/pcompare41.html?sn=d7f1f9d45ef9350586e63b691907e7e5 has a nice overview.
Just like you I would also like to see some additional kwalitative feedback from other forum-members on these two models.
For me the reasons to choose for the exr-3 are:
- positive end-user feedback on sound-quality
- decent behaviour as a midi-controller and good compatibility wiht apps like ACID, Cubase and the likes
- Key size and feel
- 64 voice polyphony (although to be honest I don't know if this is a big plus compared to the 32 VP of the Casio)
- USB connectivity
- 16-track sequencer
- I like the Look and Feel of the Roland (= subjective)
On Bart's site

p.s. does anyone know why it is so difficult to get hold of Roland user-manuals (.pdf) whereas you can just download them from other manufacturers like Yamaha, Casio, etc.
