Direct answer
What is the best mana base for a Commander deck?
Updated
The best Commander mana base is 37 lands sized to the commander's color identity: Command Tower + Exotic Orchard + a fetch/dual suite tuned to your budget, plus 2-4 utility lands specific to the archetype.

Why the answer is what it is
Every multicolor Commander deck runs the same three auto-includes regardless of budget: Command Tower, Exotic Orchard, and Path of Ancestry. Beyond that, tier the mana base by budget: check lands at $50, pain lands at $100, shocks at $250, fetches at $500+.
The single biggest mistake newer players make is running too many tapped lands. In multiplayer Commander, tapped duals cost real tempo — every enters-tapped land is functionally an entire turn behind.
