Source for 4xAA water resistant battery holder?

I'm about ready to put together my next headlamp project, but I'm short on a source for a battery box. I've checked my usual hangouts (Digikey, Mouser, Jameco) and come up short (or maybe blind?). Anyway, I'm looking for a 4xAA battery box that is mostly waterproof. Everybody has a basic 4xAA box but it's not even close to water resistant and requires a screwdriver to open, yuk. If you think you know of a source post it up.

If I can't find something I might go with a pair of 2xAA boxes, which might be more ergonomic anyway.

what about buying a dive light and soldering some wires? the uk mini q40 is 4aa and rectangular but the head sticks out
