[amsat-bb] How does Fox Delta Compare?

I was just looking at the Fox Delta model# ST3 automatic rotor control unit at www.foxdelta.com http://www.foxdelta.com/ . Seems like a good unit. The price is good. Has anyone used this unit yet. Its pretty new. Doe anyone have an opinion of how it or older Fox Delta trackers compare to other units like the G6LVB tracker, Yaseu GS-232, etc.
