Denon AH-D5000's used on amazon for $399 + $5.49 shipping. Some pics available and seems to be in good condition with some cable fraying. May want to compare to deals on the for sale forum first but I thought this was an appealing price.
Yea I bought mine before it was discontinued for a very good price and sadly I sold it on here when my collection was getting out of control. Wish I didn't as I really miss them. Now I can only find them on Amazon from Japan based sellers
