I am also at PSU-DSL now and I can't say that I agree with Melbel. Different people are of course entitled to different opinions, but I liked my professors for the most part -- especially my Civ Pro and Torts professors. I don't think students are treated like garbage -- and some professors are inexperienced, but many others are not. In any event, I think at any law school you'll have some new professors mixed in with veterans.
That all being said -- I don't think there are major differences between Dickinson, Pitt, Villanova, and Temple. I think the biggest variables should be 1.) where do you want to work/live and 2.) what type of financial situation are you in? None of those schools are worth paying significantly more than the others, since, when you really look at their employment stats, they are all roughly the same.
