Best bang for your buck for a camera

[Captain Jack]

I have a new project coming up and I wanted to pose a question to you. What camera gives you the best picture for the least amount of money. Please post your reasoning along with your suggested setup.
My choices are the C300, F3, The Red and the Canon 5D PL Mount.
The shoot will be a 10 day shoot. Indoors and outside. The shoot involves a large amount of green screening. I will be renting the camera/lenses, etc.

5D is the cheapest but I'd go with the F3 with S-log, or the C300 if that's too much.

I currently am running a 5D with Zeiss CP2 lenses. How much would a full set up for the F3 or C300 be? Do you have experience with either?

[Captain Jack]

Just found out that they both run about 400/day.
