Surly Pacer. It is a heavy bike, but it has an amazing amount of snap for the price. I think the Salsa Caserole also has a steel fork.

But, dig down on why you don't want a carbon fork. Last year I built up a custom Waterford and, while I shied away from carbon, I had no qualms about putting on a carbon fork. Forks have been carbon for a long time and the reliability factor exists.

OK, I'm also building up an S&S coupled Waterford and on that one I'm putting a steel fork. The usage of the bike is different. The S&S coupled bike will spend a lot of time travelling; packed, unpacked, case kicked around by baggage handlers; bike partially unpacked by TSA, etc. etc. Because the bike is out of my control in ways that could damage the integrity of the carbon fork I chose to go with steel. But, for my primary road bike that I take care of and pamper in ways that make my cats jealous? I trust my carbon fork.
