Paul,
I'm looking to get one soon to, want to spend about £200-£300.
Casio are looking good at the moment, on a website called
www.empiredirect.co.uk good prices or just to view specs.
I'm looking at the:-
Casio EX-Z3 £250
Casio EX-Z4 £300
These are both tiny almost credit card size and only 23mm thick, but still have an 3x optical zoom lense, digital zoom just tends to pixilate (make it more blurry)
Just great for carrying on the duke.
