What about the Roland GW-8/Prelude to compliment/contrast with the Yammie?

I'm using an S910 and that's what I'm thinking about getting.

Only thing is the GW-8/Prelude do not have on-board style assembly (you can't swap style parts) and I'm waiting to see if it gets added to the OS before I take the plunge.

That feature/function may not matter to you.
