IMO, pzhon makes a number of very good points in this thread.

As for myself, I have a low-variance style and at 200NL I don't need more than a 20 buy-in bankroll. My biggest downswing so far is 10 buy-ins, and while playing 4 tables, this leaves me with a 6 buyin margin.

I can imagine that LAGs need more buyins to play comfortable.

But playing with a roll of 10 bi's can be okay if you have the discipline to move down when you lose a few bi's. For example, when I'm trying out a new site, I deposit a couple hundred $'s on it and start out at 50NL. While building the roll I move up when I have around 10 bi's for the next level, but move down if I drop below 6 bi's of that level. The downside is that I have to move down after every downswing, which can be annoying, but still I'll never bust my roll.

I do like to have 20+ buyins though (or well - at least 15) because I'll make more $$$ if I'm never forced to move down.
