I'm playing NL100 with about 65 buyins atm,
about to move up to play NL200 with somewhat 30buyins.
And I feel underrolled. General concensus around me is that 30 buyins would be the very minimum BR for NL play.
Are we swedes possies or what? =)

And here around I see that you seem to feel 20 is good and
10 might be okay to.
