I have been using Mastering Physics as my online homework system for quite a while and I am content with it. But I've become curious about alternatives dues to cost (there are cheaper systems) as well as the fact that some Mastering solutions can be tracked down online. I checked the archives and found some discussion on Mastering vs Webassign. But now there is Sapling as well as Expert TA. I am wondering if any of you have used Sapling and/or Expert TA and what your experience has been. Feel free to reply off-list.
Thanks!
