I do it all the time....I'm in Australia so anything I sell to you guys in the US is a foreign sale....customs forms take a couple of minutes to fill in - and any additional fees are payed by the receiver. Why people complain about the forms I'll never know....

And as people have said send it registered mail (which the received will pay for), or via Fed Ex etc if they want to pay for that service....One thing I do with an international sale is photograph the box with the customs form on it, and a close up of the form, and email it to the purchaser so they know when it was shipped and the tracking number.....

I've done over 500 sales on ebay - over 90% of them have been international, and the only problem I ever had was a Japanese gentleman who sent payment via international money order, and couldn"t understand why I was waiting for it to clear through my bank because I couldn't read the paperwork that came with it. It was in Japanese after all..........

Ask them to pay via pay pal in US$ - what you do about the pay pal fee is up to you. I would rather take pay pal with their fee than take a international money order/check which my bank can charge anything form $15-30 to cash...plsu it can take a week to clear....

I wouldn't worry about Singapore - the culture there is generally very honest (we've not talking some places to avoid shipping to - on ebay I prefer not to ship to Africa, Italy, Indonesia and parts of South America)..
