I have just finished my parts ordering for a UCS 10179. 21 Bricklink orders, 1 Lego pick a brick order, 1 Lego bricks and pieces order.
Total parts cost $917, postage $170. I live in Victoria, Australia.
I found shipping from UK is barely any more expensive than Aus. Shipping from USA was a bit pricey.

Last delivery should arrive tomorrow YAY!
One thing I did to find the cheapest price was use Brickficiency. After the first run I removed all parts which were available in less than 80 stores. That then gave me 3 stores where I could order 3/4 of the parts.
I have drawn the radar dish sticker in Adobe Illustrator but am not sure where to get it printed yet, since the aim is to be printed on a clear sticker.
