cheaper on our own?

i had always thought that it would be cheaper if we went on our own to dive sites in malaysia instead of through a singapore operator. however, based on many of the figures i have seen on the malaysian operators websites, for the same period, a full board package would be cheaper but it also has less dives and we have to make our own way to the various dive sites. by paying about S$50 more, the entire trip would be packaged and settled by the singapore operator. pros and cons. haiz.
