Marshall LCD70MD-3G vs SmallHD A7-SDI vs Ikan D7w

I need a good on camera monitor for the Black Magic Cinema Camera. Has to have SDI-HD ports on it to connect to the camera. And it has to have markers or frame guides to help with framing properly for broadcast TV. I prefer video scopes as well to check exposure and other things. I know a lot of people usually prefer the IKAN but it has no markers. And the SmallHD doesn't have the video scopes/added features the Marshall or Ikan have. At the same time, the Marshall isn't 1280x800 like the others but seems to have all the feature for professional broadcast video production. I'm leaning towards the Marshall right now. Thoughts?
