These carbon steel pans by Matfer Bourgeat have received a lot of attention after being featured by Cook's Illustrated as one of their most highly rated cooking utensils, and as one of the best pans to use for cooking. They were in short supply for awhile, so the prices stayed high.

However, if you plan to get one, you should first read about properly seasoning it first as well as understand that as a carbon steel pan, it needs more care than stainless steel or aluminum pans with regards to drying after being washed. This will last a lifetime, like tri-ply steel pans. These will sear foods better than tri-ply pans, and will work on induction cooktops (not all tri-ply will).
I recommend the hot oven method of seasoning with a very, very thin wipe of oil. Then repeat, repeat, repeat to develop a harder coating. The stovetop oil/salt/potato skin method recommended by the company did not seem to add much of a seasoning layer to the bottom and left uneven seasoning along the vertical edges. The pan is thick and heavy (61oz., compared to 38oz. for an All-Clad, and 27oz for a T-Fal non-stick aluminum), but less fragile than a cast iron pan (which can crack).
