Hi Shark girl,
we really can recommend Divine Diving! We already have been travelling and diving around Indonesia several times and always have a look at new places we have never been before, while combining with places we already have been and liked most. So Flores/Komodo is really a 'we like to come back' place!
The diving is great and as we also went diving with another company in our first times there, but we switched to Divine, and this year is going to be our fourth time to dive with Divine Diving.
Marij (the owner of Divine) and all of her staff are always well organized, very helpful and trying to make you feel as comfortable as possible. There are always experienced instructors and/or divemasters guiding the (small) groups, depending on the customers diving experience, so no worries about diving safety (including lifevests and Oxygen on board).
Usually we went for daytrips, but last year we did the a 3days/two nights diving safari as well and it was really fun and worth doing it! So we are going to repeat that as well this year!
We have never done 'real' diving liveaboards, so for us there is no need of luxury, our main interest is the diving. But even the boat is more basic, you will have everything you need and maybe more..
About the gear I can't say much, because we have our own equipment, but it always looked well maintained and we never heared of anybody having problems with it. I think Divine Diving is really reliable.
Hope that helps a bit,
Darja
