Mine was a little over $200 IIRC and has saved me lot of time with manufacturer-specific issues already that my cheap OBD2 scanner would just say 'no error codes'.
Positive Feedback

So often you're better off getting a cheap tech2 or forscan interface instead of an expensive scanner that still might not have as much functionality.
