The cheap one will usually work ok for one device. The output is pretty 
weak so you need to tape it right over the sensor. The high power one 
will allow you to control several devices from one emitter.

To find the frequency. Find a lirc configuration for your device and 
look at the top of the file. The frequency is shown in the info there. 
But in actuality, it does not matter as long as you install the correct 
conf files for your device. The config tells lirc what freq to use.
