I am looking for a Tuffpak 1050TSA myself.
I did go to order one direct from Nalpak but the shipping costs, to my home in Australia, were limited in options and nearly the same as the cost of the Tuffpak and their base price mysteriously jumped up considerably when the exchange rate was applied and to an amount in excess of the exchange rate.
So, I figure I will be better off if I can find someone who no longer needs their Tuffpak and can send it at the cheapest postage/shipping rate - I am not in a desperate hurry for the case.
