I have only used this monitor on 3 video productions and it is still in excellent shape. As a bonus, I am including two batteries, an HDMI cable, and a carrying case, all of which were purchased separately. Below is the description from B&H where the monitor kit was purchased brand new for $629:
This ikan D5 Kit includes the D5 5.6" monitor, Canon LP-E6 battery plate, sun visor, shoe mount, and power supply.
The D5 features a 1280 x 800 HD resolution and 3G-SDI and HDMI inputs. It offers an essential set of monitoring tools, including Peaking, False Color, and Pixel-to-Pixel, for setting up and fine-tuning your shots. A headphone output is available on the bottom for monitoring audio while you shoot.
The monitor has a rubberized texture exterior that provides a better grip as well as trendier look. All the controls are located along the edges and rear and include a rotary navigation wheel, an input button for switching between live inputs, and three function-assignable buttons.
The included battery plate is interchangeable with different supported ikan plates.
