Buy In

[macdona1]

I play at a local casino 3-6 and usually just buy in for 60 dollars. I would like to play higher and I definitely think that I have the ability to as well, however, I am a college student and need the money for other things. Anyways, I have had problems recently with running low on chips if I lose even one decent sized pot, the only time that I can really play my game is if I win a decent sized pot early. Any reccomendations on what I should buy into the game for considering my limited bankroll?
