Gran Prix Cycle in Albany, Oregon is a sponsor of the board here. I just checked their inventory and they have a low hour used '07 ec300 listed (listing isn't really clear whether it's a de or an ec...)
From the photos - looks like it is in great shape.
By the way, the '07 has several advantages over the '06 - new subframe, a tad lower and bike is lighter than '06. Others can provide more details here.
