I'll be honest, I have to agree with Ivy on this one. This topic has been rehashed a number of times. And to be very honest, I'm not sure from your post what information you're looking for zesty.
But, if you have a particular course in mind, search the archives here. I can guarantee it's been discussed ad nauseum and you can probably get some good ideas. Aside from that, use a search engine, such as www.google.com
and do a search for LSAT prep courses. When you find one worth checking out, come back and check the archives for that.
