For the best running discussion about LSAT prep that I can think of, check out www.nontradlaw.net
and its discussion board. Go to NeatGin's excellent LSAT thread. Nontradlaw.net is a good site in general. As the name implies, it's populated primarily by non-traditional law school applicants. Many have long been parents or are changing to a legal career later down the road. Accordingly, there's much much much less PR-style one-upsmanship, braggardry, and sciolistic bull.
