I haven't seen any other reviews of mpb in the USA, but I took a chance and it turned out OK. I sold my Canon 70D, 18-135 stm, and 15-85. They were prompt answering emails and acknowledging the receipt of my shipment. A little slow about getting back to me once they had my stuff (they promised to respond in three business days, I hadn't heard from them after four), but they replied within minutes after I emailed asking about the status. They paid me what they said in initial quote. I also asked for quotes from B&H and Adorama. B&H took three days to get back to me and quoted less than MPB. I never did hear back from Adorama.
