Honestly, Viking has nothing to worry about his tags because this is not a con case, willing buyer, willing seller. When Viking asked TS to refer to the pictures when he asked about the PDA's condition, he could have requested for more clearer pictures from Viking if he was doubtful about anything instead of concluding the deal in a rush and make a big hoo hah out of it now. Do take note that this is an used item, some scratches and imperfections are pretty normal. If you buy an used car, if the owner tells you that his car is accident free, I'm sure you don't expect the car's paintwork to be of showroom condition because it's accident free.

Viking has offered a sensible solution to you and I can frankly tell you that no other sellers here will be willing to replace the casing for you since cosmetic imperfections don't affect the functionality of the PDA. I suggest that you just accept whatever Viking has proposed to you. He has been very sincere to solve this matter with you unless of course, if you have a hidden agenda.
