Yeah, it doesn't have a brand on it. If you're getting one, just look at the thickness. Mine's about 1/2 thick (maybe a little less) and it's lasted about 10 years for me now. I've heard of the thinner ones breaking or shattering over time. Mine is 16" in diameter.
It wasn't expensive, just a kit from a store like Bed Bath and Beyond that had a stone, wooden paddle, pizza cutter...
FD, bring a box of wine for the wife and you're invited.
