I wanna buy sony DSC W55 digital camera.but it is a new model,can u suggest me if any other gud model?

here's a link on ebay where you can read reviews of them by ebay members

What's wrong with the W55, it's an upgrade of the W50.

There is the W30 and W50

In the same class is the Casio Z60 and Canon SD600 and there is also an Olympus.
