For $200?
Sorry but there is nothing I would recommend in that price range.
I run a Sony wireless setup with a Lav, Handheld, & Shotgun options but it cost me about $700 (+ the shotgun & hand mics) and that's just running one mic at a time. A quality dual system will cost over a grand.
I have no idea if there are even any options in that price range but if there are, they will be very poor quality.
