Well, I was going to drive up to Ohio today, but something came up. Next opportunity won't be for a few years. I'll check in and see if you still have them, thanks.
I just got back from Lowes. Cheapest steel door they had is $104.00. It's solid core - the guy told me that it is polyrethane filled. Don't know what that means, but it seemed pretty solid. No damaged doors, but it seemed like it would be a good building surface.
