To put it in perspective, that's about the same cost as a five year old work truck with 150,000 miles on it. For the same money you could also have four bare bones modern sporting rifles.
I have a suspicion that the price tag won't be a barrier to the sufficiently motivated.
And as with all technology, the price tag will drop and quickly.
Not if, but when...
Hopefully, everyone will understand and see that we are ALL more secure with this defensive material being distributed.
