They are made from my home stae of va, which is a plus. They do seem high, but to support local might be worth it.
I live in a small farming community and understand the value of supporting locals, but to pay so much for what would be questionable as ever receiving that value back in its uses, I don't know.
If you want to support a local, find a fabrication shop that is a real local (from your own town) and show them the video's and have them make you one. I'm betting they can do it for less (time and material, you supply the ammo can).
