Got my 5600CL-1ER yesterday, love the classic look and the red scheme (was a strong point why I bought this version. Red = doesn't destroy nighteye = good within military). More expensive then the regular 5600 though. Had to buy at abroad to, was not available in Sweden.
The strap which is made of leather and nylon is very comfortable.
Here are some pictures, sorry for the quality, haven't got myself a systemcamera yet.
Rough use anyone?
Forgot to put a classic zippo in the picture though.
My first casio was probably the w-725, still working, but one button is living on it's last life.
