On a recommendation somewhere on here, I bought a Matfer Borgeat carbon steel pan. I love cast iron like anyone else here, in part because it can be used on any fuel source; campfire or stovetop. And you can pretty much treat it like cast iron. But it's quite a bit lighter, yet still heavy enough to be bombproof. My cooking isn't broad enough to need a set of pans; I'm usually sauteing or frying whatever it is that I'm eating, so one skillet serves 90% of my needs.
Now, having said that, I will be checking out the OXO unit!
