Roger Machado BJJ any good?

Does anyone here go to that gym for BJJ? Ive been looking into it, not sure if I should just pull the trigger and join. Theres no prices listed anywhere. Is it any good? is it expensive? If it is pricey, is it worth the money? I love BJJ and have been wanting to get back into it for a while. Im still a white belt but left my old gym because the instructor was bad. Im looking for a place to develop solid fundamentals
