there are a lot of options in your price range. I have a Canon S45. I've flogged that little guy to death for 4 years. It's relitivly small, good solid metal body and fully manual options. It fits snuggly in the pouch in a CamelBak Mule (for example).
I took a fall in Sedona. landing square on my back, the camera was between me and the ground. I dented the front door over the lens but the camera came through like a champ.
I did just manage to just kill it, but that's because I got caught in the rain. I forgot about the camera in my pack (with the rain fly still on) so it got very wet as the moisture migrated through my pack. I think it can bew repaired so all is not lost.
I have a few friends that like their A series canon's as well.
