Used V-Synth keyboard or new V-Synth GT?

[Wireframe]

So what are the advantages of the newer V-SynthGTs over the older V-Synth models? I can see the control surface is a little different with a couple new controllers as well as the color screen.

Are the GTs worth the extra $1000 compared to a used older model? It's difficult to compare the two at Roland's site.

the GT has 2 original v-synth engines builtin. so you have much more processing power with the GT
