Henry,
I too got the 268 and the free BAR122HGLA from Ambient. Mine does not have John Deere on it though. Mine has the Oregon Scientific logo. Whatever the logo, I agree that it is a great little addition to my system. I love all the Icons like you mentioned. I am also hoping it might be usefull in diagnosing dropouts when they happen. You can't go wrong since it's free!
If you want a small and easy to read satellite console go for it.
