Another one here for improvising with a foil wrapped brick, or weighting down with a CI pan. Sometimes I'll just turn up the heat a bit and smoosh the sandwich down with a steel spatula and hold it there till it gets a nice crust. I'm cooking for one most of the time and don't need another small appliance - although I argue with myself about it sometimes.
Rick, I don't bother heating the brick.
