UCertify Software any good?

SmootCIS

I am looking for inexpensive software to help me study for this one. I have previously passed the 270, 620 by the MSPress books and would like to use something a little more interactive on these (being that the subject matter on this one is more new to me then the previous 2, and I would rather have a practical knowledge of it) I came across the UCertify website it looks pretty good, and cheap anyone here used it? Or do you have any other suggestions on what to use?
