I've heard of some people having trouble with Paypal but I've had much used account with them for well over a decade and never had a problem with it. I just purchased an item from Australia and Paypal did the currency exchange thing with no problem at all. They also gave me the price based on that days exchange rate so I knew what it was going to cost me in american dollars before I completed the transaction. You do need some time to set up an account with them because they need to verify your bank account so don't wait until the day you want to purchase something to set up a Paypal account. For overseas transactions they'll add a fee to the buyer if they use a credit card, but not if you use your bank account.
