The Z3 was released in Jan of 2003.
The Z30 was released in Feb of 2004.
The Z30 replaced the Z3, the Z3 is now out of production.
The Z30 has several improvements over the Z3.
One is the better flash coverage. (11.1 feet instead of 7.5 feet)

Does anyone know the difference between the Casio EXILIM EX-Z30 and the Casio EXILIM EX-Z3 models? The only difference I can find besides the looks, is the Z3 model is generally $100 more! Thanks everybody.
