Ref : Health Insurance

As a fit & heathy 55yr old, i will potentially be coming to thailand on a Non-0 or LTR Retirment Visa, my initial research suggests a good comprehensive health insurance policy can be as much as THB 10-20k pm. Is this correct?

Also can anyone recommend any good policies and/or broker, i'm looking for a comprehensive policy with no nasty exclusions, would prefer higher limits and the best coverage

i have not ruled out Thai Insurers, but would prefer the most extensive types of policy

thanks in advance

Sorry if this question has been answered before but I'm researching this question on Google and visa websites but it's a little vague:

How many times can you renew/extend a 90 day non-immigrant O visa; additionally, what's the difference between an O and an OA visa. TIA.
