I have been planning to do my IDC in Phuket as well, so I am very interested in this topic.
At the moment I am considering these options:
Scuba Cat
Bent Posejpal (also the course director for
Sea Fun Divers)
Chris Owen at
Indepth Instruction
and
Björn Tackman at
Dive Asia
Of these, Bent and Björn somehow seem the best alternatives - and I'm sure Chris will be as good a choice as the other two. I get the feeling ScubaCat caters more for the backpacking hero crowd, but they offer
free diving! on their boats before the IDC program, plus a
free liveaboard! .
I haven't made up my mind yet. Somehow I'm tempted by the idea of diving for a few days before the IDC, and taking a liveaborad trip after the IE before I start working (I already have a job waiting) - but then again those things are kind of irrelevant as I want the best instruction I can get.
I am sure that all the shops will tailor you a package that includes only those things you need and want, and nothing extra.
