I'm studying on a budget, seriously! Local university has the Todd Lammle's CCENT: Exam 640-822 2008 (minus the CD) online which I just started studying. Are there any other suggestions you can provide to supplement this reading? I was looking into the Boson SIM eventually. Also, I was thinking of getting Wendell Odom's just because it has the CD. I'm trying to budget under 100 bucks but 50 would be better.
