So i pulled the trigger and picked up the "core" for $54 on amazon. Its a great mouse, feels longer than what you're normal mice are. I was hoping the scroll wheel would have the older style "lock" and auto free spin function but its manually switched between them. The freespin is good but the wheel needs a bit of balancing because its almost too smooth and it will roll back/forward on you when you take your figure up. The "course" scroll is crazy - like a washboard lol. Anyway, all in all I'm happy with it. Performs well, software is working well although i haven't tested the macro tool.
