Nitrox certified. A waste of money. I've got 3 tanks O2 cleaned, a waste of money. I'm an air hog and don't get near my NDL limit. I don't feel any different diving EAN or air. I wish I had the money I spent on the course and the O2 cleaning. I may never dive NITROX again.

1) You'll primarily see a major NDL benefit when diving repetitively (esp squarish profile) and multi-day.
2) Feeling different isn't really a criteria. You absorb less nitrogen on a given dive parameter, nitrox verus air. All that matters is that you're less likely to ever 'feel' the need to check-in at your local hyperbaric...
3) Air consumption can be improved.
4) There's always sidemount, or for the olde-skool type, who like to invest in stainless steel... back-mount doubles. Ample gas supply just makes a dream match with nitrox..
I wonder if the fact that this thread has made Nitrox sound complicated is going to turn off the OP from pursuing the Nitrox cert? I can't believe anyone these days seriously frets over whether to get a Nitrox cert.

If you are diving shallow, but long and repetitive dives than the pulmonary toxicity of Nitrox may be a disadvantage and unless you are reasonably close to NDLs you are getting no benefit. Risk > benefit.
Incorrect! Wikipedia: "Pulmonary toxicity result from longer exposure to elevated oxygen levels at normal pressure. Signs of pulmonary toxicity begins with evidence of tracheobronchitis, or inflammation of the upper airways, after an asymptomatic period between 4 and 22 hours at greater than 95% oxygen, with some studies suggesting symptoms usually begin after approximately 14 hours at this level of oxygen."
Pulmonary toxicity is not relevant to SCUBA diving.
