We have done several Aggressor boat dive trips, (along with other brands), and about 3 dozen live aboard dive trips in total...some of the boats have been replaced, 'shifted' to other dive destinations, etc., so my talking about a specific boat may be old news.
Before I get into a long post reply, here are some questions:
-How long diving/being cert'd? How many dives? Ever in Caribbean, in real open water? Do you like deeper/multi diving per day? Do you, (and spouse/partner) want to do 4-5 dives a day for a week? Good conditioning?
Not that live aboard diving is 'rigorous', but it is pricey and there is nowhere to go, and not much other stuff to do, once you are 'out there', other than dive. Very different from a shore based vacay.
Some links, if allowed, for reading:

Will be glad to give you my opins, though specifics 'two years from now' will possibly be quite different from today, as the economic pressures on these companies is enormous at this time.
