Thank You for your input. I am out of state right now and am having trouble with my email so I can't contact Steve.
I will be in D.C. this weekend so I'll try to stop by Barry's. I checked the web site but the effect isn't listed (at least not as the magic compass.) I'll call in the morning.
I think I'll also try and find some copies of the Trapdoor.
Thanks again guys. If you think of anything else let me know.
