Xrite i1xtreme and EFI ES-1000

[pacart]

So i would just like to know if anyone has used the Xrite i1xtreme branded machine on an EFI Feiry Pro 80 box? I have a konica c6501 and would prefer to buy the Xrite branded version as it is less than half the price ($1399) of the EFI ES-1000 branded version ($3000)? Does the EFI software still pop up or is it identical to the Xrite software - just rebranded?

Any experiences would be helpful, thanks.
