You are correct about the PAR being a military only thing now but it is a very useful think to have in an emergency.
If you have a total electrical failure a PAR will get you on the ground with ILS accuracy using only a hand held radio........ Or may be a cell phone.
As the UK has an integrated aviation distress system in the UK it is likely that if you declared an emergency in a light aircraft you could probably find a Military PAR within 30 min flying.
