Just so, Marty. I travel indepentent, so can't really speak to the issue of dive masters, but once last year when Sylvin Forman couldn't take us, he hooked us up with Rudy at Bottom Time. Nice, small operation, good boat, and a great ladder to climb up on (I love my Sylvin, but he has a gawdawful ladder, as I've yapped at him many times - he's not going to change it). But, Bottom time gives you a smaller boat, and a good ratio of divers to dive masters...like 4 or so divers, except on a busy day, to one dive master. It works for me.
