NNT's pricing is moderate - I would rate their pricing two-and-a-half out of ten. There are no additional costs, they include the entire package in a single license.

Definitely understand the FAST service up front and determine whether you will need it, as that impacts pricing slightly.

Consider both their on-premises solution and their hosted solution. Both are reasonably priced.

We have selected a perpetual license along with support. It's part of the overall package. It's all in one.
