OK, here's the straight poop. One adapter, in a box by itself, will cost US$6.20 to skip across the ocean to Australia or New Zealand. I didn't price multiples in one box but finger on doubling that price and it will probably be less.
So, shoot me US$11.20 and I'll drop one in the chute for you. I like Paypal, dimlight65@aol.com is my Paypal thingy.
{edit} Oops, I forgot to say yes, they are the downdraft adapters.
