After reviewing lots of mini casting furnaces online I chose the GG 2000. The price, capacity and size worked for me. My hardest decision was picking between the 110 or 220 volt model. I figured the 220 volt model would melt the metal a lot faster but I would have to wire a outlet just for it. I chose the 110 volt unit so I would not have to do any special wiring. I have used it 3 times now and amazed how quickly it melts aluminum. 20 minutes and I am pouring. I could not be happier with GG 2000.
