Does anyone have experience using Google Checkout. I am looking at this for counties where Paypal and Moneybookers are not available.

I have used Google Checkout for buying products online, but that’s about it. Worked fine. By the way have your heard about 2Checkout.com? I haven’t used it personally, but I think they deal with virtually any country except for:
North Korea
Cuba
Iran
Sudan
Syria
Myanmar (Burma)
For obvious political/economic/humanitarian reasons, 2Checkout.com doesn’t deal with the banking institutions of these countries, but other than that I think it’s pretty global in scope!
