I had a similar "overhead burner" type raclette cheese melter with a single tray when I was catering. It did not have a "cradle" for the cheese but a wire frame that held the chunk of cheese in place on a metal tray. I had to have a step-down converter with a receptacle for Euro plug because it was from Germany.
When I first started Jurgensen's market on Ventura Blvd. carried both Swiss and French Raclette cheese but when they closed, the only place I could buy it was the Cheese Shop of Beverly Hills or the cheese shop in the L.A. Farmer's Market - but the latter was often sold out or didn't have a whole wheel. (There was a discount if one bought a whole, uncut wheel)
I gave it to a friend who was doing some catering in the ski resorts - Big Bear, etc., - very popular for the apre-ski crowd.
