There are other decent bedliner products out there other than LINE-X. But, you may not get the "whole package". For example, when choosing a bedliner, consider the product, warranty, and tendency to fade.
So, for Xtreme:
Product: Polyurea/polyurethane blend, high pressure.
Warranty: Lifetime, but not nationwide lifetime.
Fading: No UV protection offered (I don't think).
If you plan on putting on a tonneau, don't worry about fading.
