Here's a stab at it:
GPS was entirely funded by the US Dep"t of Defense, so no cost to the users. You might check this out:
USAF GPS Fact Sheet
Ground-based navaids are highly variable as to cost. First, there are siting issues: leasing land, site preparation (leveling the site, road construction, foundations, etc.), then there is the cost of the navaid itself. An ILS installation, I understand, runs about $800,000 minimum without approach lighting, double that for the ALS. Many more difficult installations go multiples of that figure. A VOR is probably half that, but that is a guess. DME is co-located with the VOR, so the only additional cost is the DME transceiver. TACAN was funded by military organizations and provided DME, but, I suspect, the military isn't funding any TACANs. NDBs are the cheapest, but probably none have been installed in the last 15 years, as GPS is replacing them. NDBs have very little need for site work prior to installation, while the other aids have standards for level ground, trees, access, etc.
Construction is the big upfront cost, especially in difficult terrain.
