Bankroll questions

[sng-sam]

I am mainly a one table tournament player but have had some recent success in 1/2 NL ring on both stars and party. I'm quite sure that I am underbankrolled. So my specific question is.

what is the needed bankroll for ongoing regular ring game play at this limit. I know that I want to buy in to the game at 100BBs but I'm thinking more long term. For example in single table tournaments the belief is somewhere between 30-50 buy ins. Would this be a good place to start for NL ring? Thank you in advance.
