I have sold a few times to overseas buyers. Try to avoid it if I can but a sale's a sale. The problem I had was undercharging for shipping as asking for an additional $20-30 hardly seems worth it after the item shipped.
If the buyer is an ebay member I would insist on paypal payment and increase the shipping charge. You can easily refund the extra.
