I've read good reviews about Tivoli tri ply stainless steel cookware (as an inexpensive alternative to brands like All-Clad). At TJ Maxx they have at least 3 different "models." They don't give any model names but one has hard black handles (the least expensive), one has black "comfort" handles, & one is bell-shaped pans with metal handles. Since the reviews I've read don't seem to differentiate between the 3 types, I wonder if anyone has any more info about the differences between them (other than of course the handles). Thanks!
