Differences between the 3 Halliday textbooks

[rakrobn]

What are the differences between the 3 books below? Are they all pretty much the same? I wanted the text that would serve well for independent study for General Physics I and II and with not just plug-and-chug problems.

What is "extended" in that edition compared to the regular edition?

In reading posts, I've heard that getting the 1st or 2nd edition would be good (I don't know if that refers to the text with Krane as the third author or the book with Walker as the third author.)

Can't go wrong with Halliday, Resnik, & Walker. Some problems can be quite challenging, though there will be some plug and chug.

I haven't worked with the Krane text, but I have heard good things.

As for the edition, I have the fourth and seventh editions of HRW and many of the problems are exactly the same, and the older one only cost me 20$ with a student study guide.

The extended is if your Gen. Physics course contains a third or fourth term on modern physics, but normally professors use a different text for modern and it is normally a separate course outside of gen. physics...it's really not worth the extra cash for the extended, pick up tipler's modern text or Renik's quantum text instead for the last few chapters of HRW.
