Watch the axle-to-crown height. You can get rigid forks (sometimes called "suspension-corrected" or similar) that are made to set up pretty well with frames that were designed for the taller suspension forks. Droy45 is right in his post that the geometry can be an issue, but you can get past that with the right rigid fork, they are not all shorter.
