Please take a look at high carbon steel pans (carbon steel pans is a different name for it).

It's very simular to cast iron but just weighs a lot less, no teflon or other coating. You do have to season it if you want to use it optimally (but this just takes a couple of minutes).

'De buyer' is one of the top brands for carbon steel pans. Ikea has decent ones too for a smaller price if you just want to try it (I exclusively use the ikea high carbon steel pan myself).
