Sharkman,
Just in case you get second thoughts about hauling your gear though airports, explaining what a regulator is to a scornful security agent, or other weakening influences, try this.
Next time you dive with a dive shop, stick around after the dive and see how they clean regulators. Then imagine putting your mouth on those regs! Or see how carefully they clean wetsuits--need I say more?
Oh, yes, one more thing. As my camera gear began to take over my baggage, I had to shift my regulator setup to my check-in luggage. It's been a year and a half now, and, so far, (touch wood) no one has lost my gear. Now, I admit that I am less concerned than before because I now have a Stinger and the computer in my consol is the backup!
