The OP is asking about two products that dudadiesel doesn't make. I am sure he is thankful for you pointing out that you got a great deal and love your plate chiller, but he isn't asking about dudadiesel.
I have seen a chill wizard in action and it seems to be a plate chiller with a pump built in. Not sure if that is what the real difference is. Good luck with your purchase, I am sure you will be happy with either purchase.
