Just guessing but because of the wording used here I suspect the case on the 60 to be different than the ones for the 75 and 250 "DNA 75 and 250: Choosing Black for buttons will drastically reduce your lead time. Matte Black cases are out of stock and will drastically increase your lead time. DNA 60: Choosing Silver for buttons, and Black, Red, or Blue for the case will drastically reduce lead time. Edit: I see that I misinterpreted as saying (60) Black, Red, or Blue for the case will drastically increase lead time not reduce lead time so now I have no idea.
