I love half.com. I buy a lot of books, cd's and software there. They're part of Ebay and very reliable. Good luck.

I plan on checking these books out to see if i can find them. Thought someone else would be interested.

I am lucky my local library carries all of them! I usually check out the books from the library and then decide if I want to purchase them.

Thanks so much Chance for the info about half.com. I never checked them out before. What a great find! Thank you!
