Give us some examples of what you deem ridiculously expensive.
In the Florida Keys, out of Key Largo last September, I found a package with Rainbow Reef Dive Center that basically added up to $600+tax (& tip) for 10 2-tank boat trips, tanks & weights included, with no added charge to follow the guide who was in the water for every time. So, $30/dive + tax & tip, with tanks, weights & guide. Awesome.
Also better than charter boat pricing I've seen anywhere outside of the Florida Keys. If I'm on a cruise in the Caribbean and do a 2-tank boat dive, I expect to pay close to $125 + tip for similar service.
Some charter offerings farther north in Florida look cheaper, but take a closer look; tanks may not be included in the price. By the time you rent tanks, it adds up.
So, explain what you think a dive trip ought to cost, and perhaps folks can give you some feedback as to whether your expectation is realistic.
Richard.
P.S.: With OW, not AOW, you need to check with the op. whether you'll be allowed to do all the dives on a given trip. Fear of legal liability leads to requiring AOW for some dives, particularly in the U.S.
