If anyone has a Sigma 150-600mm Canon Mount (Contemporary---NOT Sports) that is say, within 1 to 3 years old in very good condition priced in a "motivated seller" range then I would be interested in hearing about that. I see that these are selling on Amazon Brand New for just under $750.00 with full warranty etc. By "motivated seller" I would expect at the very least a 20% discount (or more) to what I could buy it for brand new.
Thank You.
