A bunch of people are making binary proclamations about whether one or one doesn't need to do an expensive course, but before making a decision people really do just need to read what you wrote.
Before plopping down thousands of dollars, ask yourself: Were you a good resident and/or fellow? Did you get a great variety of cases during your training at a true tertiary/quaternary center? Were your ITE scores good? Do you or did you do a lot of practice exams with strong academic faculty, particularly those who are board examiners? Do you have access to board certified anesthesiologists with whom you can practice? Are you a good speaker? Did you immediately sprout flop sweat and almost sht your pants every time you had to give an M&M in front of a big room?
If you look at those questions and you have the non-reassuring answer to a majority of them...then yeah, maybe doing the expensive ubp, job, or ho course may be for you. If not, just get the UBP books, memorize the answers but know that they are a guide and not verbatim as they are too long and detailed, do 6-10 full practice exams (preferably with BC faculty or examiners), and you'll be golden.
