Hi,
I also bought an overseas Nook. It has not arrived yet (hopefully tomorrow). It took me 6 months and last month (at last) I decided to buy the nook. The most important features I have taken into account were the epub format and the possibility of including a SD card.
So... I took almost the very same steps than Atomix. I used Borderlinx instead of Shipito and I cannot say if it was cheaper or not because i ordered a couple of things more and included them in the same package.
I paid with paypal and I had to phone B&N customer service to make sure the Nook was delivered. They knew I was overseas (I suppose they control all the fowarder addresses) and they wanted to highlight I could not buy any book from B&N if I was not in the US. I said I did not care and they sent it.
In case you are interested in buying a nook: Us_unlocked has a very good how-to in this blog:
