Um, the best way to withdraw it depends on where you are I think. If you are in the USA your life might be a little hellacious getting it out but as long as the casino is good there shouldn't be a big issue. I know a lot of people use wires there.
If you're international, definitely Neteller if you can, or Moneybookers/Skrill. A lot of casinos can do those withdrawals the fastest and then you can just transfer to your bank from there for not a lot of money.
