Aterpster, one of the reasons its so damned expensive is the its farmed out to "contractors" and a bloody great RJ is used for the certification flights, there is a ground unit used by the military which can do it for about 10% of the cost, in the mean time we will continue with our "in house" straight in.
I've never heard of a ground unit that can do as well as flight inspection.
A lot of the costs, particulary for procedures with Decision Altitudes, is the cost of on-site surveys.
