Are you needing a 3 channel system to use on a variety of camera systems? If so then we would recommend the MK3.1 receiver.
If you are needing a versatile 1 or 2 channel system we would recommend The Latitude MDR-M or MDR-MB receivers. They will do everything that the MK3.1 Receiver does with some added features and future proofing technology!
The MB is exactly the same as the M except it also has a battery plate so it can powered from an LP-E6 battery.
If you are using ONLY DSMC2 camera systems we would recommend the Latitude Sidekick as the best option. This is three channel compatible and fits snugly onto the side of the camera body.
