they do not seem to be a reputable organization. i purchased a lens and tried to return it but missed the return period by 2 days. they sold me the lens in "like new" condition. i never used the lens outside of my home and it was attached to my camera a total of 10 minutes to test. i decided i needed a longer focal length and since they wouldnt take my return i decided to sell it back to them. they offered $490 for a lens i spent over $600 on less than 10 days earlier. i took their offer and returned the lens. now they changed the quote amount to $460 due to "condition" it was returned in the same condition as sold to me in the original box. if there was a condition issue it was sold to me that way. i caution anyone who does business with MPB to be careful, they are rip-offs and i would never consider doing business twith them again!
