My husband and I dive Maui every year (we own a timeshare there) and we dive with Ed Robinson's. They tend to be geared more toward the independent and experienced diver than some other ops. Other good choices IMO would be B&B Scuba and Mike Severns. Frankly, you wouldn't go wrong with any of these three for boat diving.

For guided shore dives, I've heard Shaka Doug is really the best. I've also heard good things about Maui Dreams, but Shaka Doug in his "scuba bus" is known for his excellent personalized service.
