Any problems selling equipment outside of USA?


I've recently been contacted by a British man about buying my amplifier through Escrow.com. What kind of problems are there in shipping and completing the sale successfully? What role does Customs play? Does anyone have experience with this? I'm not sure how safe I feel about this.

I have sold to Europe, Canada, Guam, Korea and Japan. No problems ever. People are either honest or not, nationality is not the reason.
I've done it several times, but the only way I've done it is to ask for a funds wire transfer to my bank account for the agreed-upon amount before shipping. The first time worked perfectly (Hong Kong) and the second was going beautifully until FedEx shipped the package to the Phillippines instead of Korea and delivered it to someone, but obviously not the buyer. Still trying to unravel that one!
For private party, after the deal is finalized,the best way to handle the transaction is to have the buyer wire money to your bank before sending the amp.
I live in United Arab Emirates and have bought and sold many things on Audiogon sometimes to/from the US and others to Europe. No problems, the same rules apply. Sometimes sellers worry about customs. You see the customs are the responsibility of the buyer. So the most that you would do in enclose an invoice describing the item and the market price for it. And if you want to help the buyer reduce the cost of customs you should reduce that value.
I sold my speakers (Snell A/IIIi totalling over 300 lbs) to a guy in Italy. I wasn't too keen on the process, but the buyer knew what he was doing and contacted shippers himself. He wired the money to me and the shippers came for the speakers (I had the original boxes) and everything went smooth from there. Letting the buyer arrange the shipping has the advantage that he/she is better equipped to handle the customs problem.
