Mike here are a few look a likes (and real examples) I caught in central IL.

Contrast enhanced pic of what appears to be scud in contact with the ground. Near El Paso, IL on July 13, 2004

Non rotating wall cloud over Peoria IL, March 30, 2005
Rotating wall cloud near Jerseyville, IL, June 13, 2005 (the same storm John Farley posted a pic from).
Let me know if any of these would be useful for you and I can e-mail the full resolution shots.
