WANTED - TC-20E III AF-S Teleconverter

[SnappingShark]

Interested in picking up one of these as inexpensive as possible!
They're $500 new, and I would like to use it on my Nikon D7100.

If nobody is selling one - is there anybody who is willing to lend until the beginning of the new year?

Thanks for your time!
J


I can trade for a 18-105 and a 55-300
