I'm thinking of opening it as well. so far I had two 5d MK2, one 7d and xti - none of them had issues with funtionality. It's really hard to resist opening it while I have it on hand.
Agreed with the temptation
After this saga, I decided to hop on the Amazon train and scored the kit for $3300. Sold my old 24-105mm for $650. With that on the way, temptation is ressitable...
BTW, I already sent the kit back to BigValueInc.
