I have a really bad snob problem when it comes to cookware,I have several thousands of dollars worth of kitchen gadgets. Heck I have TWO Kitchen Aid mixers. Le Creuset and All Clad are my fav for pots and pans (who has the All Clad chefs pan,I love this).
Anyway, I just had to say that I bought one of these cast iron griddles for my sister's then boy friend as an xmas gift a few years ago and it was very heavy duty with one side ridged as a grill and one side flat for pancakes and such. It was from Target or
Walmart. Your talking untreated cast iron here. As long as it is heavy and thick there is NO differance in quality between one from William Sonoma and one from Target. The one Ray Ray has looks EXACTLY like the one I bought for dsis's ex-bf #47

.
If your going to buy enameled cast iron that is one thing, but this grill pan is just a big slab of cast iron, if you buy name brand your just paying for the name. If that's what your into, more power to you, but I'd rather save the money and buy something that makes a differance in actual performance, not just to have a name brand.
Also FYI. Please don't buy cookwear from Bed Bath and Beyond. The All Clad they sell is very low quality. It is for people who have heard the name but don't know what they are looking at. If your looking for cookwear go to a high end cook's store, talk to the clerk. Let them explain the real deal with the product your looking for (for example copper clad pots are a joke). Than when you know what you really need and what actually WORKS. Go buy it on line cheap( buy an $80.00 knife from the clerk so his time wasn't wasted, some of them work on commision).
