I have a casio ex-z500. I got a great bargain at Singapore airport though I can't for the life of me remember the price.

It's a great little thing that has a massive display screen. It's brilliant for what I use it for - playing around with silly photos mostly. It's 5 mega pixels as well.

The only trouble I have had is if you press a lot of buttons really fast it'll freeze up (which I have an annoying tendancy to do).

I think the things that make cameras so much easier to use are the quick start up time (if your looking for quick passing shots) and something generally easy to carry around.

Oh and the less buttons, generally speaking, the easier it is to use and thus...for the most pasrt...idiot proof
