Canonical Minimal Dice Set

So, what's the canonical minimal dice set for people who play D&D? What dice could we expect pretty much any D&D player to have, or easily and quickly acquire even in remote areas lacking a game store?

Here's my thoughts:

• d4, d8, d12, and d20, probably two each, possibly even different colors. 
• Either two d10 of different colors or one normal and one labeled in multiples of ten.
• Multiple d6s of at least two colors or two sizes.

I figure the d6s fall into the "easy to acquire quickly" category, since I've even seen standard dice in gas station quickiemarts.

Any contrary opinions?
