I sold equipment to Adorama recently. I got less than I thought I would get, but I thought that it was there, and I did not want to go through the hassle of getting the equipment back and selling it myself or sending it on to B and H or other company. It took well over 1 month from when I sent my package to them to when I received the lens I traded it in for (closer to 1 1/2 months). It took them over a week from when I confirmed that I wanted to trade until they actually sent my lens! This was unacceptable to me, and coupled with what I feel was less than what my equipment was worth, will NEVER be purchasing from Adorama again (B and H all the way for me).
By the way, the same day I confirmed the sale with Adorama, I made a purchase with B and H. The B and H package came before the Adorama one even shipped!
