Yes, we are using ES to setup and download our yield data cards from GS1 and GS2 JD components.  We can also write prescriptions in ES and upload them to both GS1 and GS2 components.  The only hiccup is downloading the GS2 field operations.  We couldn't download our GS2 planting operations this summer, but ES is testing this in a beta version that will be available shortly.

Another reason I scrapped Apex is due to how long it takes to download yield data from the GS2.  With a large farm, you'd better get it started in the evening and come back the next morning and hope everything went OK.  In ES, the GS2 yield data takes longer than the GS1 data, but it's only by a few minutes.

As for cost, I believe ES is $995.  You can go to their website for details:  http://www.mapshots.com/
