Don't know anything about Sunset.  I dove with Caribbean Sea Sport last
year.  I thought they were pretty good.

I dove on 11-26-04 with Andy Loefstok of Dukes Diving.

Did a couple great shore dives, the drop off from shore is so quick a
boat is really Not necessary.

We limited our first dive to 60', vis was about 100+

The wall is so steep you dive your depth guage-- so if you wanted a
deeper dive its NO problem (but you  need greater surface interval if
you desire two dives)

Maybe a 15 minute ride from the cruiseship dock... I brought my own
gear less tanks and weightbelt --  his shop has lots of gear & is right
on the water.  I would not hesitate to dive with him again

I live in the Lower Keys and dive regularly and it was fun to dive
somewhere so different than the Keys. (A shoredive/wall dive was very
different for me!)
