Steve Ray recommends it.
From the product description, it seems awesome.
But insanely expensive
I don't think that it is insanely expensive. One is only around 500.00 and the other is only 700.00 or so. But look at all the resources you get. The only thing that I wish that they would add would be more works of the Popes. For example, there are 14 volumes of our current Pope offered in a separate resource. I wish that they would combine the two. I could do without Martin Luther's 95 theses.
