For SNG you need 50 BI's to be in the comfort zone, IF you're a winning player. 60+ if you're not.
I'm assuming you're not, so I'll say that you need at least 60.
If you have $60 and you need 60 buy ins, what level do you think you should play? It's basic math man.
For cash tables (ie. 1c/2c, or 2NL) if you buy in for 100BB's, that is $2 for each buy in. If you want 50 buy ins, how much money do you think you need in your bankroll to be within proper BR management rules?
Why is this so difficult for you??
If you drop below your 50 buy in limit, either drop down in stakes, re-deposit, or start learning how to win.
If you are a losing player, it does not matter how well you know BRM. You're just going to go broke slower. Stop focusing on this subject and start focusing on how to win.
Stop asking this same, very basic question in multiple threads. Do some thinking for yourself. Use a calculator if necessary.
If you feel you are not getting the answer you are looking for, ask again in the same thread that you posed your origional question, don't keep starting new threads about it.
And please, for the love of god, use paragraphs, capitalization and proper punctuation in your posts!!!
