The Trek steel 900 series were one of my favorite frames to ride. Years ago I was in love with a green, lugged 930 with a rigid fork. It was in the Trek "Singletrack Series" and it had super tight stays and a shorter wheel base than my 7000. That bike was awesome on the rocky switchback trails in northeastern PA I grew up on.
It sounds like a solid bike, they are a good deal even today.
