I went with the Surly fork when replacing the crappy low end suspension fork on my Trek. It's chromoly but still weighs a whole lot less than the suspension one I removed. Price was 100 bucks from Ultimate Cycles. Surly makes several different part numbers for disc or rim brakes and also to compensate for the different length of the old suspension fork. It's called the Surly 1x1 fork, just choose your appropriate part number from the descriptions. In my case, no cutting of the steer tube was needed. It was a simple 15 minute job to install with a couple of Allen wrenches.



Between the weight removal and the gain in efficiency form the loss of the pogo effect, the fork really transformed the bike.
