If carbon scares you that much, then I won't even bother to explain the benefits of it. However, if you want something that I think is better than steel for strength, but also won't rust...
Titanium.
If you know your size, and shop around on Ebay, you can get a new lower end, or used higher end Ti frame for pretty decent prices.
Nothing is out of reach if you really want it, and do your research.
