The Modern Ag system was just under 80,000 $. The 1 catch is it won't load up plan files. This ag system is just for drainage and won't load road jobs. On the grader they could tie into the existing blade pro valve for $3,000. The other 3 machines "set up" was just cab mount kits. The Leica system is a base, a rover, an external receiver, rover pole, and a cab mount kit. It was 33,000 $ It's another 30,000 $ to hook up automatics on the blade with it. I would like to try a simple surface program for the data I get surveying, not as simple as getting an app on your phone.
