Has anyone used this hot plate before? It's portable and only $30. I want to get two of them for what will possibly be a one time job (flambe station for a 100-person party). I don't want to lug anything huge around or put down too much money since I'm not sure if I will get a lot of requests for this or not. I thought of trying to rent something, but I can't find anywhere that rents equipment like that. Any other suggestions?
