Last month after looking at about every brand I installed the Raymarine Evolution Auto pilot on my prairie , the system was an excellent value , it worked perfectly out of the box and functions just as well without the rudder angle feedback hooked up. the seatalk allowed me to let it talk to my gamin over the n2000 cable so i have speed an depth on both lower and upper control stations. I also went ahead and purchased the wireless control and it works great also . with current technology almost all are good i would think but for value it was best bang for buck I found.
Additionally the heading sensor seems to be electronic instead of a ball in fluid like the old styles so i am thinking the thing should hold up longer. as those were generally a weak link my total cost for unit, 2 control stations and wireless was about 2500, I reused the existing pump and rudder sensor (that is still disconnected btw).
