What's the bankroll requirements for heads up SNGs? How big are the fluctuations compared to 10 person one table SNGs?

If this has already been answered before please provide some links. If not, please give me some estimates. Thanks.

"What's the bankroll requirements for heads up SNGs?"

Depends on your advantage, but 20 buyins should be fine, and 30 is plenty.

"How big are the fluctuations compared to 10 person one table SNGs?"

Significantly smaller.
