Well, people usually use egold only if they can't use paypal for te same purpose.
If you thought it is cumbersome enough to withdraw paypal funds, wait till you try withdrawing funds from e-gold!
I think e-gold is next to paypal in terms of availability and user friendly services. I mean, that is how I see it personally. Google checkout might have a chance to make it in the near future, but that is still a doubting fact.
MoneyBookers definitely because it accepts members from all over the world. Less fees as compared to Paypal. The customer support is good and the withdrawals are very fast. E-Gold is also good and can be next to MoneyBookers.
