Hi Peter,
You might try survey supply shops. I've seen them carry these Ricohs in the past. They're not distributed to the usual consumer shops. In fact, Ricoh cameras are barely distributed in the States at all. The terrific GRD and GX series are available at only two dealers (who, oddly, don't carry the weatherproof models).
In my experience, slrs are more susceptible to cold-related failure, and odd behavior, than compact cameras. I suspect there are several reasons, expecially that they draw more current (to operate displays, large shutters, autofocus, etc.) and have more and larger moving parts. Compacts, by contrast have tiny shutters, no swinging mirror and don't have to stop down the lens when shooting. The only compact disadvantage I can think of is power versus manual zooms.
I suspect regardless of the camera, it's helpful to turn off the LED display, which is a power hog.
In pre-digital times some makers, notably Nikon, Leica, and Hasselblad, could winterize cameras for customers headed for the poles or the high mountains. IIRC this involved, among other things, removing grease and replacing it with light oil that doesn't thicken in the cold. Such services might still be available for all I know. Remote battery cases kept warm in a parka pocket were a popular accessory for cameras with electronic shutters and onboard meters (fully mechanical cameras avoid this completely).
For anybody who wants to shoot for extended times in the wet or cold, I encourage a close look at weather-sealed dslr bodies such as those by Nikon, Pentax and Olympus (there may be others) paired with sealed lenses (e.g., all of the Oly mid and top-grade lenses). This doesn't resolve cold power issues, but will give assurance of protection against both the weather directly and the frequent condensation resulting from using a camera stashed inside a parka.
