Seriously Mike? Most of the time I think your advice is pretty good but believe you've tripped over yourself on this one. Anybody that has done a number of discover scuba dives, especially with one dive to 100', is going to find snuba a real snooze.
Go for certification since you've already been bitten.

You sound like a good candidate for snuba instead of scuba. Remember once you're scuba qualified you're expected to be able to be self-sufficient with no supervision. That takes a commitment of time and money to develop those skills and keep those skills fresh and remain safe. Snuba would be better if you just want to occasionally over long periods of absence, get underwater and enjoy the experience and scenery in a safe and supervised setting without worries of keeping skills fresh to keep yourself safe and alive. If you can't make the commitments of time and money to scuba, I would avoid it and pursue some of the 'scuba'-like experiences available that fit your situation better.
