Law School Discussion

Without discussing the merits of online law school, I have already decided that's what I will do. I am planning on sitting for the Wisconsin bar. I will get a significant raise at my current job if I have a law degree. So having a substandard degree is not a problem for me. The question is: Which online degree is the quickest and cheapest that Wisconsin will accept? Alternatively, is there another state I should be looking at? Thank you
