I have dealt with Marc in the past on 3 seperate 
occasions, and so have a few other people I know, 
and we all had good experiences with him! ... so 
I guess "deal with him at your own risk."  I'm 
sure he's completed many successful sales, but no 
one ever get's on the forum to praise someone 
these days... it seems like people only post 
complaints about a seller... such a shame.
