The cheapest way to find any out of print book is to peruse your local book exchange. The Book Exchange in Cranford, NJ has an excellent selection of science fiction and fantasy. I found several of the Vlad Taltos books there. I know it takes alot of time to go through used book stores, but remember, the journey is half the fun of getting there. I often find that I go for one book but come home with totally diferent books, all of them treasures that I had been searching for.
