Moniker seems to offer the best deal for .asia domain names, but it's very frustrating trying to purchase one. I've gotten more than one error message when I try to use PayPal, such as "null null" or "Unable to verify PayPal purchase." Moniker tech support is blaming it on PayPal, but PayPal has worked fine with other transactions. Also, they charge an additional fee for using PayPal.
Are there any other reputable registrars that offer .asia domain names for less than $12? Godaddy and domaincentral are expensive.
