Any math nerds here know of a good place to get a slide rule? My brother has been looking for one for ages and I agreed to help him out. While looking for one, I have gotten an itch to get one for myself. Of course I found one for him today (2 bucks at the thrift store), but now need to find one for me. Any ideas for a good place to find a cheapish (20-30 bucks max) one online? They seem to be like razors-- astronomical prices in many places...
Any ideas?
