Not that I have the money or strength to travel right now but if I did I'd go with Nancy Klimas. I know someone who has improved with her and I like the fact that she tests your anaerobic threshold giving you the number you need to pace safely so at least you won't get worse. I always keep in mind that if money could fully cure M.E. then the WPI would never have been created by billionaire parents of an M.E. patient. That doesn't mean that the best treatment money can buy can't improve you significantly.
