Hi guys and gals! Im doing my CCNA by myself and I was wondering if anyone can recommend a good router sim which I can download? Your help would be greatly appreciated!

I've never used it, but this was returned as a first result from google: http://www.semsim.com/ccna/learn.html

I just bought that 2 book set last week, and have to give the CD a try. I will post again here when I get a chance. $40 on Amazon for the 2 books and CD.
