I received an email from Sur La Table that Demeyere Industry5 is on sale today. Very tempted... as I am looking to upgrade to some better (5-ply) cookware from the eclectic cheaper (really cheaper!) pieces that we have. Any input on experience would be appreciated. SLT has a variety of skillets, saute pans, and an "essential" pan on sale Also, how does Industry5 compare to Viking Professional 5-ply? Thanks.
