Thanks Jeff, the bag costs from $81-$169 and worth every penny from here.
http://www.drybags.com/home.htmlThese bags are definitely hard core, you can dive with them down to at least 200 feet, I keep my sleeping bag in one and solar equipment in another but any configuration will work. The cell I got was $310 from a guy vitabon off of e-bay and they usually start at $300, he always has them. It's a 40 watt cell. If you get a bag add the purge valve, it makes it real easy to adjust buoyancy.
