Have a look on B&H, Adorama, Reduser.net, Dvxuser.com
I really liked the anamorphic modification of the Helios 44.
I think that the black magic video assist is a good monitor 1920x1080 and a recorder on cheap SD cards in ProRes 10bit 422. Very good price!
Some idea of the price range?
The size sensor is a shame, it will be tough for the wide shoots.
C100 with an external recorder like the Black Magic video assist, or if you don't have enough money forget the 1920x1080 monitor and take just the ProRes 10bit 422 with the Atomos. Otherwise a DSLR 4K, Sony or Panasonic.
