PC on Req9 15>50 Shadow Bow

Hi, I'm in the process of trying to pick up one of these to complete my req9 15>50 bow collection. How much can I expect to pay? I searched the forums, but there seems to be a very large range in terms of price...

Thanks in advance,

Mil

Bump...

these seem to be picking up in value, some selling for 100k+ now
