Alright I just pulled the trigger on the Roccat Kone+ $117 shipped
Thanks for all the input everyone!
Cons: cable is little bit too stiff. a little bit too heavy (at least for me (126g(?))). not very easy to lift up unless you have sweaty hands. avago adns-9500 sensor is a little bit jittery on cloth mouse pads.
Pros: Everything else.
