I was doing some searching for Pro-Log manuals on the internet, and I ran across this web page from ADVANCED VEHICLE TECHNOLOGIES, Inc. where they have some books and manuals that they didn't want to throw out, so they are giving some of it away, or selling some of it very inexpensively http://www.avt-hq.com/books_01.htm http://www.avt-hq.com/contact.htm I've already gotten just the two Pro-Log manuals. They also have some surplus hardware for sale. Some of it is inexpensive. http://www.avt-hq.com/surplus.htm Best Regards
