Online Texas Hold'em Deposit

The minimum PartyPoker.com deposit is $50.
You can deposit using Visa, MasterCard, eChecks by iGM-Pay, NETELLER, WesternUnion, FirePay, Citadel, Wire Transfer or Checks by Regular Mail.

I can personally recommend Neteller. There are no fees for direct deposit and the tranfers are fast. (1-2 days) You can withdraw your winnings and deposit from Neteller directly into you bank account for free. Some credit cards have issues with Casinos so consider Neteller as an alternative. Use the PartyPoker "Cashier" button at the bottom of the PartyPoker Page to setup your real money account. One note about Neteller, you will probably have to call and talk to one of their Customer Service Security personel before they activate your account.
