Difference between 640-507 and 607??

I found a book for CCNA (thanks for the help guys), but before I got it I noticed that this one was for exam # 640-507 (older CCNA?). I double-checked Cisco's site and noticed that the exam number is now 640-607. Would this book be any good? The exam objectives look close, but since I don't have the official objectives for 640-507 I don't know how close they are. I checked Cisco's site and they seem to be the only one to offer a book for 640-607, at Sybex's website their newest is 640-507.
Does anybody know of a good Cisco simulator? I only have access to an old 1004 ISDN router which seems to work for some commands, but I don't think it will be enough for everything.
Thanks alot for the help.

From what I've read, the 607 exam contains the same material as the 507, but some of the problems (like those that require you to choose commands) are now interactive Java applets. So, instead of selecting the appropriate command from a list, you will have to enter it into a command line simulation. This will definately make the exam more challenging.
