OpenStax Algebra and Trigonometry

Has anyone used one of the OER remix services? I'm looking to pull a few OERs together to make a custom textbook for a string of Math courses at the college, and wondering if anyone's had any luck there. I've been looking at LibreText mostly, but open to recommendations/ideas. Main reason for building a custom textbook is to have something to show admin; content links are fine, but less easy to say "here's the book".
