I keep meaning to buy a set, but they are so dang expensive.

Though, I'll admit I have purchased several 'classic' CS books over the years that have been sitting on my bookshelf, unread, for an embarrasingly long period of time.

You can buy pdf copies on informit.com. If you wait for major holidays (black friday is best), most of the books will be 50-60% off.
