Panini grill or cast iron?
 

I received a Le Creuset grill pan for Christmas this year, but I'm
trying to decide if I should 1) exchange it for the Cuisinart
"Griddler" panini maker (that does much more than panini) or 2) get the
Le Creuset panini press that matches the grill pan I already have (it's
like the bottom of the grill pan, but you put it on top of whatever you
are cooking in the grill pan itself).

The appliance seems very convenient, but I don't like the idea of
having yet another device to store. The grill pan and press looks
nicer sitting on shelf, but I think it would take considerably longer
to cook with and to clean.

Does anyone have any thoughts about the utility of either one?
Thanks!
