Really trying not to turn your thread into an infomercial for Red Barricades but could you expand upon you reluctance to purchase Red Barricades?
If I still had my kit I think I would ship it to you as a loan just to give you a taste of this remarkable module. Unfortunately all I have are a couple mapsheets and Fish's RB rules which I am reluctant to part with.
Good luck and enjoy whatever you decide to play with.
You should check out the King of the Monster Scenarios thread just to see the RB/RF combination scenario. It's beyond impressive!
