If you add in the cost of keeping an electronic subscription for charts/maps, the cost is even more exorbitant.Government; however, the format read by the various GPS/FMS's is proprietary to the manufacturer and no one else can compete.
My airport has the GPS Alpha and VOR Alpha approach.
Hoosiers are up-to-date on all of the newest artists and can always take you to the best show in town.
With so much great live music going on nearly every night in Bloomington, concerts offer a great change of pace to the typical romantic dinner date.
I have avoided buying an electronic flight bag for exactly this reason.
When you buy one of these systems, you are "married" to that format"...better, or worse.
