I use the Home Edition which I bought for just under $300 a while back. It is a great mathematics playground, although, concerns over being able to peer review the engine or calcs in the software are valid, not for what I use it for. It is like Emacs for me. I leave it open all day, and just play around in it. The multiple programming paradigms are fun too for coding practice.
