Team 701 uses the CNC masters Supra. It works very well and gets the job done. I have had zero issues with it. It comes with a mastercam package but I prefer to make the CAM files in inventor then export to mastercam.
Here is the link for the machine:

Good luck with any parts that your team CNCs out in the future.
