I've got the Stylus (known as the Mju here in GB), I was able to get the camera, PT-016 housing, extra battery and card for just over £300. It'll get used 47 weeks of the year on dry land, where it excels, and underwater it provides pretty good bang for buck in my opinion, in a pretty small package.
I added a UR-Pro colour filter and I have been very impressed with the cameras capabilites so far.
