Looking for the best Deal on a .450

[imthemedic]

I am looking for a 16" .450 Complete Upper. I was getting ready to pull the trigger on the Cabelas deal and then it was gone the next day. Does anyone know who has the best deal on one. I was going to get that one for 550 shipped. Or better yet does anyone have a used one that they are wanting to let go at a discounted price?
