I have an aeon scope on my compatto. Its a really nice scope. I think I payed near $400 for mine back when I got it. I have seen that PA was selling them really cheap some time back with the sold as is. I wonder if they are simply dropping the brand for some reason. Nothing unusual when it comes to retail an PA is good sized.
Anyhow. Its a great scope and for the asking price its more then worth it.
