Well one of the main things to consider is what you are going to use it for. There are many instances where you might want a single transmitter to go to a couple of receivers and many can not achieve this. Then there's the type of signal- ie HDMI (paralynx arrow, asus) or HDSDI (Teradek Bolt, Camwave, Boxx Meridian). If you want to encode your signal and stream it then there are many other options for live events and Teradek Cube.
Then there's price, weight, reliability, FCC regulations, range, ability for line of sight, available mounting options, latency, whats available in your city.

Latency is likely to be a major problem. Just about all of them use some sort of MPEG4 compression, which means there is a considerable processing delay, because the endoder needs to snare a complete GOP (Group Of PIctures) befpre it can make each transmission packet. The theoretical minimum delay is usually around 1/2 second, but in practice it can be much longer.
This is no problem if you just want to stream pre-recorded material from a Blu Ray player or the like, but hopeless for live monitoring.
If it's just live monitoring you're after, old-fashioned composite video is probably still your best bet.
