Speaking of which, I learned a thing or two at the Expo in Portland. 
	1.  Found a supplier of low voltage lighting and miniature cameras 
that might be useful. Mostly he sells to the miniature ROV and commercial 
diving communitites for lights, but it applies to us. Lights for <$100!.

	2. Electrical penetrations come in different levels of certification 
these days. Sounds obvious after I saw it, but the ROV industry has allowed 
the creation of less expensive penetrators--on the order of $30-$60 per each 
dependant on pins and load requirements. "Man Rated" for certified pressure 
vessels are still the high priced glass filled, etc., etc., that cost $300 to 
$600 and come with pedigrees enough for the AKC. My point is that even the 
cheapest plastic (epoxy filled) units have 600 psi ratings and might very 
well do thee job in our 60 to 150 psi environments.

	3. Inexpensive phased-array sonar systems are available that offer 
visibility to 600 feet and better. Not a bad idea for the lake divers and 
nearly essential to go and actually find something in the ocean.
