I haven't yet used the one from The-Good-One, but it looks pretty cool.
I have owned all the models of Diamondplates over the past few years and love them. Next one I get will have room to add on one of the Good One's units as well.
If you have a chance to come out to the Cook-off next Saturday, March 7th, there will be several of each type out there to look at.
Hope to see you out there. Let me know if you have any specific info you want on the Diamondplates.
