Storage of Gold

I have been reading Jim Sinclair's blog for a number of months. He recommends storing gold outside the US, preferably in Singapore. I have been storing mine locally, and feel nervous about having it so far away in someone else's hands. Storage costs will also add up a lot over time. On TF Metals, everyone talks about "stacking" which I assume means buying and holding coins myself, which is what I have been doing, and prefer to continue to do. What do you guys think?
