The Primus was mentioned. The newer version of this that shares the Prodigy platform is the Primus IQ. Same workings as the Prodigy except the display is limited and you can't mount it upside down. If you are on a budget, this will function as the P2 P3 series without the whistles and bells, but as has been said, once you get it set, you don't know the trailer is back there.
I had a Voyager which is pendulum based and while it worked well, it was just not real smooth. Changed it out for the Primus IQ and have been happy. The Primus IQ gets overlooked, probably because of the name and association with the old Primus series which was pendulum based.
