Super clean Shimano Dura Ace 9000 series SRM. 172.5 cranks, 50/34 rings, PM7 current firmware, as well as the necessary magnet.
Battery was changed recently, and was used mostly indoors. I've got some screen shots of the powermeter functioning, and Garmin shows the battery status as "New".
Let me know if you'd like any photos. $400!
