<p>I'm about to order these books on Amazon but I can't go to any bookstore at the moment to try to preview these. Just want your feedback/personal experience from these books (i.e. how did they teach concepts, practice questions, etc.) so I can see if I'd like them too. Thanks in advance.</p>
<p>New versions come out soon if you want to wait a month or so.</p>
<p>Is it worth waiting for them? I know the PR and Barrons book hardly change each year, but is it different for these other books?</p>
<p>Gruber’s doesn’t change. Trust me. I have seen the 2008 and 2009 editions.</p>
