Moving to Lombok.

Vin, as for medical insurance, you can Google for that, and also post your questions here:

While Fred's opinion is to use local companies, and with all due respect to his opinion, he lives in Jakarta where there are plenty of high quality medical care providers.  If living in Lombok, I personally would be more inclined to have an expat medical package which will include that all important benefit…emergency medical evacuation. 

The trick to keeping the premiums for expat medical insurance policies at a manageable level is to take a policy with a high annual out of pocket deductible…an amount you can afford without breaking the bank.  Think of the coverage as catastrophic coverage…the kind of medical issues that would break the bank.
