What Kinze monitor did you have before a KPM 2 or KPM3 ?

What all was required for the Ag Leader 1200 to monitor the planter and what all can it monitor. Any extra modules or sensors required.

I have Kinze 3000 2014 model by serial number. Has a KPM3 monitor. Monitor seems fine not the easiest to edit or set up separate field areas. Accuracy I felt was pretty good. Calibration number I checked vs what was already entered and it was close enough to leave unchanged. Acre readouts were pretty close to field sizes only discrepancies were in overlap on end rows (no shutoffs)

What advantages is there to a 1200 over a KPM3 as far as monitoring functions and planter. I'm guessing if one went with Ag Leader guidance then having everything on a single screen would simplify things.
