Are you going to stay in another country long term? How are you going to do that? Is there any country which allows foreigners to stay there permanently? If not, add in the air ticket cost to and fro. Based on the 90 days visa available to sinkies, there is a cost of at least 8 trips (to and fro). After you include the cost, is the country still affordable in your definition? You could probably say can always go JB. Same thing, you still have to travel to and fro albeit lower cost compared to further countries, it's still cost and should be included as part of the living costs. Not to forget this is only financial cost. There is also foreign policy cost. I.e. the customs notice your increased frequency of travel and begin to monitor your activities etc. at worst, you'd be required to stay outside the country for a minimum period of time before allowed to re-enter again.
