Bonaire is a pretty cool place to dive really cheaply with a lot of fun stuff to look at if you are looking to get back into it. Unlimited dives (of oxygen or nitrox for 180 for a week) and cheap rentals as well. They would re-certify you there too. All achievable via low effort shore dives with very little if any currents. Vis is like 100 ft too.

That sounds nice, all my experience has been in the Channel Islands off SoCal.  I would definitely want to go through a recert class and will probably try to patronize one of the indy dive shops around where I live.  Did my first one with sport chalet, but they gone now.  Bonaire may be an option if my Geron bet goes wildly better than anticipated.  I just got back from burning man and that is a surprisingly expensive venture especially when you are a lead at a decent size camp.
