Wow!
I hate dishonest people. I live in KC so I googled this guy and looked on FB. He definitely sounds kind of shady for several reasons.
Anyway he has a FB account and is a member area of our local audio group (Kansas City Home audio enthusiast) and has posted his link a few times.
He also claims to partner Deva Audio (which I highly doubt) from time to time.
You could post the audiogon thread on his FB page. For the amount of $ lost I would think you should get some type of law enforcement evolved.
