The sony F65 is also a camera that is superior in every possible way, except for "size" to anything Red has put out, unfortunetely, you couldn't pay people to rent it.... A Sony rep told me that they've recently discontinued production of the camera...
Hopefully, Sony get's the marketing right on the F65 successor...
All in all, unless the work and or rental clients are lined up, and these contacts have been secured, the purchasing of a camera system can otherwise prove to be a very poor investment choice...
