I have just completed buying all the parts for GG. It took 11 BL vendors (4 from my country) and one visit to the PAB locally. I am replacing the sand green bricks with red and the dark green parts with green. It is not the best colour combo but will do currently. Already, it costs me USD 530 including shipping and minifigs parts. I am located in singapore and hence shipping costs from USA and EU will cost me a bit.
