Need to See

Looking for a cheaper math program without being able to see the products is impossible.  I can't accomplish this and feel confident about my choice.  I've looked and looked online, but all the little examples that I see are just not enough to make an informed decision.

Laura still has some of her ACE books left.  If I don't find what I need soon, I may have to stick with ACE.  I would like that, except I just can't afford to keep buying them.  With shipping, they are getting expensive.  I am trying to cut costs.  However, I can't switch to something that we both hate or that just doesn't work just because it's cheaper.

I'm still researching, but so far my time is not yielding any results.
