I've always wanted a big professional one with all the works, but that is definitely in the distant future for me. Right now I have a Lumix Mega o.i.s/24mm wide and it works pretty great and takes some great pictures, I haven't had a problem with it yet It's also nice and small, and it's held up really well through several zoo trips and family holidays

Here's a picture of the black version, mine is silver:
