The best way is to use e-gold and paypal both. E-gold is opened for everybody: paypal is more dangerous: they can limit your account, but you can easily unlock it with virtual credit card. So, PayPal is opened for everybody too - you only need a vcc.
Credit card may be the best and everybody can use it too but does it accur to you that "being able to use" doesn't mean "being able to get"? It is also not always expense-free but paypal is free and there seems to be no fee for conversion.
I have a money booker account but their system is so stupid that I refuse to buy if the supplier only takes money booker. The problem is not with registration, the problem is that their system doesn't work when you want to pay or take out your money. Support is non-existence, no matter if you call, fax or email.
