MCSA

125$ for course is not expensive at all (good W2K MCSE course would cost you 500 - 700+, don't know about MCSA, but probably the same crap).
Exam price was ~100$ but it's already more expensive (have to check), so if you're not sure about your abilities, it's better to invest in good training material/course, then to waste it on additional attempt. I've personally failed 1 exam cause didn't have good stuff to learn.
