All-Clad is showing up at local TJ Maxx/Marshalls/HomeGoods stores in the US right now. D3 (stainless steel with aluminum core) and copper core are more expensive but considered BIFL. There is also a lot of the HA1 non-stick as well. Non-stick outside of seasoned cast iron isn't BIFL according to some purists here, but my HA1 skillets have held up for years of daily fry jobs.
