If you want a relatively nice (but inexpensive) chromoly fork to match your chromoly frame, just pick up a Tange Rigid Mountain Fork in the suspension corrected version.

I have the Tange on my commuter mountain bike. It's straight-gauge chromoly tubing. About 2 lbs. Pretty much bomb-proof for commuting or XC riding. Inexpensive, too.


Some options for you (from $45 to $315):
