Lucky,
I would call that Roland US number again...ask for a manager and tell him/her what you have learmned/heard here.

Yep, you got right through to a Idiot!

At Sweetwater Sound Right Now.. GW8 is in stock $895
E-80, E-60, G70 Out of stock and a longer than normal lead time! If Roland had G70's Sweetwater would not say long lead time.
