It would be a great time to do it with prices FAR lower on the used market for displays and receivers than they were 2020-2022. 

I think you'd love the ease and integration of it since you have JD machines. 

My only question is your pre-existing lines. Digi vs SF-RTK or whatever signal source you go with.....I'd see if you could demo/borrow whatever receiver you plan on running w/ that signal. Test some of your boundary edge lines this winter. It may be right on....it may not since they use different base corrections.
