Paying yourself from online winnings

[automaton_22]

Hi there.
Looking for some advice about how best to pay yourself from poker winnings, while maintaining the BR.
I am 3 tabling 6max NL25, and it looks like I am finally beginning to turn a profit [please don't barrage me with flaming about how easy it is to beat NL25, I only play 1-2 hours a day OK?].
I am fully rolled - $522.
I am not at this point looking to move up stakes, I want to grind out NL25 and build a lot of experience first.

So how do you recommend 'paying yourself out,' when you just need a 20buy-in BR?

Am guessing cashing out $100 by check when BR hits 20buyin + $100 is one way to go?

I play at party, have access to Neteller, and live in NZ.

Any comments about bankroll / currency conversion issues / speed of payment / fees I might not know about etc very welcome.
