After speaking with Francis on ebay and arranging the purchase and shipping of a cobrahead to Australia, he showed me an extremely useful tool which will literally save me hundreds on shipping. It's called parcel monkey and it compares shipping rates for both local shipping and international shipping.

If you want a certan type of cobrahead, message him and ask about what he has, he has much more than is listed on his eBay page.

I wonder how it compares to the other name I’ve heard that is good a few times, Pirate Ship.

Which cobra did you get? The M-400A2?

Just looking, parcel monkey still seems to be cheaper. I haven't actually bought it yet (bit low on cash) but I have made arrangements with him. I will probably get the m400a2 fco, but since I am still making up my mind he said that he would keep the ITT to the side too.
