PL bankroll management

[1fineday]

Hi, everybody!

Just came home from casino, where I played $1-$2 PL. I found out that players are very bad and I'm going to continue playing there.

My question to you is what are the bankroll rulles for PL?
I used search tool, but didn't find them(

In this casino you can sit down at the table with ANY amount of chips(but not lower than $50) while playing PL. So, some guys play with $2k+ on the table. How much should I buy in? What should my bankroll be?
Will a $200 buy-in be a huge mistake, becouse we can win more, if we have more chips?
Unfortunately, I don't have enough money to have 30 $1000 stacks=)
