Hi,
It's good to know that u r interested in increasing ur diving knowledge.
It's best if u can get a diving instructor who is committed.
That's the best way to learn.
If u really want value for money, go to

Z.Ng (Zul) is a Diving Instrutor, really good one @ that.
I should know cos he's my instructor.
Did all my diving courses wif him.
He's also a friend, which in time (if you take up his services) he'll be yours
cheers
