Kenko 1.4x Pro 300 DGX for Nikon AF. All functions work on camera, auto focus, vibration reduction etc. Tried it on a Nikon 400mm lens and thought it was a little soft for small birds. Maybe that's just me. Probably good for scenery. B&H said it's best on a lens with less than 400mm but I forgot to send it back. B&H price is $224. Send PM if interested and for price.
We have lived in the same rural area for many years where our County Sheriff knows everyone. Best buyer protection I can think of.
