I know from what I hear how wonderful the 150's are and the RO's also. But I am curious those who only have the ETS 125 are you perfectly happy with it or is it so far below the 150's that its almost worthless? I would really like to weed out the answer of "just go with the 150's and not worry about it" I would really like to know a person's opinion who owns the 125 as there soul ROS not including the DTS or RTS
