I sent the dude a message saying "How does $450 plus shipping sound?" and got a "that's what I bought it for, so I need to make at least $100 on it. Can you do $550?"
Gonna have to decline that. From my research, it seems $600 + ship is most certainly a steep price. I get it though, the dude wants to make some $$$ off a bad deal.
