Would like to share my experiences with two sellers of EF 17-40 in this forum.
Had agreed to his selling price and while arranging for a time/place to meet up the next day... he sold off his lens on the very same day
a few days later
Had agreed to pay above his selling price and had actually confirmed a time to meet up the next day. But he back off the next day, saying that he wants to keep his lens.
Very disgusted by their lack of integrity. Not a man of word.
