We used Pro-tech last summner, and have no ax to grind with them. They delivered what they promised. their rental equipment, which we did not use, looked very good, much better then Amigos, which we used for the Blue Hole trip. If you are not renting equipment, it doesn't really matter about that point. but Pro-tech was good for local diving. Amigo's had a that time the best boat for long distance trips.
