Hi Edward
In addition to and supplementing your excellent suggestion, I can also recommend the message board of that web site, which is a treasure trove of information on the type's service in Southeast Asia, not the least due to the contributions of Mark Haselden and Jim Maas. Additionally, there's a considerable amount of information on the AVG as well.
