I agree with 8400 above. We plant with an integrated AT 8120 and are very satisfied with the OEM (flowmeter) setup. Also have an AT ready 4720 sprayer (wheel angle sensor) and don't see much if any difference in performance. They both work well.
Edit to add. I should add that we are always in the 4-7 mph. range with the tractor for our uses.
