Ah, I misunderstood what you were saying. I thought you meant you could achieve DIA starting from scratch for USD1,200. A marginal cost of USD1,200 for 6,200 PP comes out to 19 cents per PP, which is not very good. If you have to travel that route for another purpose it may be worth the investment, but if you already have 50K PP on NH metal I suggest trying to obtain the PPs more cheaply on another *A carrier.
