The NSBT collection making the finals did not surprise me because it's a really great series, it's very well-known, and it is pricey, so a discount like it will have makes it affordable for a lot of people. But the Exegesis Handbooks are a shock to me to make it this far! They seem to be on a true cinderella run to the finals, and maybe the championship! Can someone familiar with them give insight into their usefulness and target audience? I might have to grab that set as well with as much as it will be discounted, but I'd like to learn more about it.
