Any problems selling equipment outside of USA?

I've recently been contacted by a British man about buying my amplifier through 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've shipped several things to Canada. Both times we used paypal. It was easier to ship via USPO than fed ex, less paperwork. Everything went fine for me...
I just sold a set of speakers to someone in Italy and it was another flawless transaction, except for the time it took for them to recieve it- everything was typical. They had dealt with international sales/purchasing before so it was very easy for everyone. I even said in my ad "prefer local sale" it doesn't get any further from local than that! Good luck with your transaction, as long as both parties have good feedback and are patient it shoudl be a piece of cake(and a learning experience to boot). ~Tim
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.
We have done dozens of transactions all over the world...We always follow the same routine no matter where the items are going (overseas); have the buyer do a wire transfer to your account before you ship. We use USPS Global priority on small items and fedex on larger ones...we have never had a problem.
I am glad to see shipping around the world is positive. I reside in Canada and have had no problems. I have found some people a little hesitant at first, but after they find out it is really no different than shipping domestically (other than declaring what you are shipping), it goes well.
I have done about 95% of my transactions outside of Canada. The majority with American customers- has been a pleasure doing business!
Canada and the States is a different kettle of fish, since there is so much trade between the two and there is a FTA. Usually no customs duty simply GST (7%) plus PST (here in Quebec 7.5% on top of that), plus some handling charge, all based on the value converted into Canadian funds, which is the buyer's responsibility at any rate.

For other countries, the situation may vary. On the shipping end, the only thing required is a declaration of value, type of merchandise and the like. Should not pose a problem.

The one great principle to remember is "Get the money". Insist on payment prior to shipment. Moreover, insist that the buyer acknowledges that once shipped, the responsibility is his, so that insurance for the full value is required. Then, if you follow another poster's suggestion, you get into the problems with any discrepancy between the amount declared for customs and the amount declared for insurance. You may think it's fudging, the authorities usually don't look upon such a practice with such a generous perspective.
