    Thinking of getting a new compact camera...

    OK, so a compact isn't going to give the sort of results you get with a DSLR, but what do you experts think - is the difference really all that noticeable these days? I've heard good reports about the Sony HX9V. Anyone know it?

    Bugs in my shower

    best rechargeable option Fenix TK-10

    Welcome to CPF, mirror. Being a far-sighted moderator who attempts to anticipate other members' actions, I foresee that you will soon be making a post with a question about rechargeable batteries: However I'm pretty sure you will ask this question in the LED section, so I'm going to move...
