Sorry for the delayed feedback Nick.
I sold Nick a pair of HD650s. I have met him a few times- this time for the exchange and a cup of coffee. He is as pleasant of a guy in person as he seems on headfi.
Regarding the transaction itself: I have dealt with him several times and he is as considerate and hassle free as they come, both as buyer and seller. I look forward to dealing with him in the future- perhaps to re-purchase my 650s
