I found a new outfit called Camerashield USA (http://www.camerashield.com/index.html) that has an inexpensive enclosure that a whole slew of digital cameras will fit in. I haven't tried it and I'd like to see if anyone else has any experience with it. (I was using the EWA bag with my camera, but my kids lost the metal closure device, dammit).
Oh, even though it is supposed to be inexpensive, I haven't been able to determine the price. I gotta make some phone calls.
