All of a sudden I am on a Michael Crichton kick. I've often wanted to read him but never been able to for some reason. Now, thanks to the marvel that is the Internet and more specifically places like Amazon Marketplace, I've been able to get most of his novels in first edition hardcovers in new or like-new conditions, each for under 5 or 10 bucks. Score! Now, the luck ran out on his five earliest novels: The Andromeda Strain (0394415256), Terminal Man (0394447689), The Great Train Robbery (0394494016), Eaters of the Dead (0394494008 ), and Congo (0394513924). I'm looking for a little help from the good folks around these parts on locating any of the above for a good price. I realize the newest book in this list came out the year I was born, but still... some sellers want $100 give or take $50 for some of these I'm looking to spend something a little more modest.
