Pick my cam?

The 360 can take a 200 shot on a regular basis if the bottom end is in at least good condition and not even built.

The cam recommendations, Ill leave to more experienced people but I will say one thing.
CALL and talk to whoever you might be leaning towards and tell them the details of your build and what you want out of it.
If they don't have time to talk to you about it they don't have time to take your money.
