Bonaire is probably tops. The friction point being that it's priced according to western standards. Example, renting a vehicle there (a truck probably as the car rental places I've seen on-line prominently display "not for diving") is easily ballpark $2,000 a month. Just a scooter, monthly, is $400. Rent another grand or more. So on and so forth.
I believe Indonesia and the Philippines have laws against solo diving. I know that people do rent tanks in Amed, Bali, Indonesia, and do solo dives, but I'd like to stay within the legal framework.
Thailand. This is the only place I can think of. I believe it does allow solo diving, the caveat being that of having one's own gear (I do), and simply renting tanks as needed simplifies the matter. Kata Reef in Phuket is an easy, quality, shore dive. Koh Tao of course.
We all have our preferences for doing the things we do. I'm a bachelor and I love doing me, solo and free. Just want a nice inexpensive place to step out when the mood strikes, blow some bubbles in a beautiful, safe-ish environment, and carry on with the rest of my day. Not really interested in what the world at large does, or thinks. May pick up a solo diver qualification at some point if I can see it providing some value somewhere. Am leaning towards Koh Tao at the moment...
