I lost my rather expensive Canon a few years back and a camera borrowed from a mate got a total soaking in Argyll. Now I use an outrageously cheap Praktica DC Slim 3.1 Mega Pixel. It cost £10 from ASDA two years ago and is small and ultra light. The viewing screen on the back is rather too small and difficult to use in strong sunlight, but it has close up and landscape settings and a strong digital zoom.
I just stick in a BIG memory card, shoot a LOT of pictures and pick the best ones. If it gets soaked or lost it is no big deal.
Works for me.
