I use an olympus stylus 1050sw, because i got a great deal on it (150). Waterproof (great because i also fish), shockproof, crushproof, and a tap control to use with gloves.
overall i love it. i wish i had an updated model with hd video. the camera does struggle under some more challenging light conditions, but it does real well in good light. my favorite thing is its size, large screen, battery life, and all metal construction. its bobmproof. It also uses a lightwieght battery and i own 5 of them, purchased for about 3 bucks each on ebay.
Also, it uses a good memory format that is small and available for cheap.
