Brian,

I did a quick Yahoo search and they don't show anyone with that user name.. Here's the thing call the phone number and talk with the guy..

He's playing the old game of if I can use your name to get someone else to lower their price.. which tell's me they are either new and don't know everyone talks to each other or he's some one that's out for you and simply wanting to stir the pot..

My vote call the phone number..
