I have been using Joseph Alai based on Ladya advice and love him.  I do also like Andrea Schulman. 
I used Lanie Stevens for LOA for the POI but people on this board have begged the question - does it deepen the emotional chord on your end?  Meaning - do you feel more attached after doing the exercises?  I feel like it probably works on the person.  but I also do feel it strengthened my emotional attachment. Not saying its not worth it,. just anecdotal input.   
I found staying away from lanie worked better for me and working on manifesting a healthy love and relationship is a better choice for my mental health 
 
 I have been manifesting a lot lately!!!
