Alpha Eagle (owned by Gentex these days), and the Gentex HGU-56 are both around $2000 USD ex USA, in a dual visor configuration with the usual mic/earphone set-up.
Looking at at least 4 for the company now. Mandatory for our company ops shortly. I have always worn one regardless, other than early on while doing tourist ops.
What is your life worth? Everyone to their own though.
