My S500 went to crap on my trip to Alaska. Nothing to do with water or UW. Just wore out. I have a perfect WP DC800 UW case, a bunch of memory cards (8 & 1 gig Ultras, 512, 128, two 32, 8 meg), 4 batterys, and 2 chargers (one with dual pins). The WP-DC800 goes for $230 on Amazon. All of the above for $100 plus flat rate postage ($11.35)
