Has anyone taken Ron Fisher or Sarah Fink for the LSAT test masters prep course in VA/Washington DC?

Hi, I am going to be taking the LSAT soon and wanted to enroll in LSAT classes. I've tried Kaplan, it was horrible for me. Now I'm looking at Test Masters, has anyone taken a testmasters prep class, and would recommend it? Also, has anyone taken these instructors Ron Fisher or Sarah Fink the VA and DC teachers and who would they reccommend? I could not find any reviews for them online. Someone PLEASE HELP!!
