Some time ago I tried to get a handle on the cost of installing ILS and my recollection is that in the US they install them for somewhere between 1/5 and 1/10 of what it costs here. I also believe that the main costs here are AsA costs.
I don't know the costs of an ILS in the US nor anywhere else for that matter but I do know they are resource intensive to maintain compared to other nav aids. One reason the US dived down the WAAS (SBAS) path with such gusto was to reduce the number if ILS's thus reducing cost.
What is a disgrace is Australasia has been so slow to adopt SBAS, but that's not part of this discussion.
