Yes, the logical choice is the Odyssey 7Q. Other choices are the TV Logic 5.6 in (Has waveform built in) and similar ones by Small HD. There are also a whole bunch of much cheaper ones. If you buy a cheap one, make sure it has enough features to satisfy you (features like waveform, zebra, peaking, center magnification, false color, various markers, audio meters, etc.) You may end up with both a monitor and an electronic viewfinder. But before you buy anything, study the Odyssey 7Q. Don't buy the Odyssey 7. You will regret it later.
