Jesus, $120? Does it knead, stretch, and top the dough itself too?
Seriously, is it really supposedly that much better than my £15 cast iron 'stone'? (I put a lovely seasoning on it initially, but didn't look after it very well and it's all cracked and flaking off, so I need to start again really I think - I suppose it does save that maintenance work... but still, I could just buy a new one and start again several times for $120!)
