oh.... and one other thing.... the GW-7 was made at Roland China and the EXR-3 was made at Roland Italy. The keyboard feel on the EXR-3 is crap compared to the feel of the GW-7. The keys are actually straight aswell, some of the keys were slightly warped on my EXR-3. The key feel is very solid and straight.

I think the GW-7 has the same key action as the Juno-D.

And dont forget the GW-7 has a D-Beam if you like those...
