I have been told, and I've just confirmed, that you *can* get ModuMath in a "home" version, for about $200.00.
This is what we have here (the institutional version and a lot more expensive ;)) and it's the best math software I've tried out, and I've tried out a lot - though less in the past year or so. It's for older students and adults and it has actual *instruction* with visuals (not just somebody drawing out problems with symbols - concrete examples of the math concepts).
