I never used the casebooks, so I never bought them. I saved the $$$, because those can get expensive. Also, there is rarely, if ever, any analysis in them. If I needed to read a case, I printed it from Westlaw or LEXIS (free for law students).
I went to UB Law School. It was a lot of fun, basically an extension of college. That is a comment you will not hear about too many law schools. Many of my friends, who went elsewhere, hated law school. My wife, a lawyer, also had a miserable experience at New York Law. Be careful where you choose to go. Also, UB was MUCH cheaper, I finished paying off my loans 2 years ago. My wife has another 15 years on hers.
