I think it really all depends on what YOU consider a "decent" law school.
There are those who think anything below T14 isn't worth the time and money, and there are those who are perfectly happy to go to a second or third tier school with good local prospects... It just depends on your perspective.
You will definitely get in somewhere. Applications seem to be a gamble no matter what your numbers. Also, I think it's worth noting that the people who post on these boards (if everyone is telling the truth) don't seem to be representative of the application pool at large. All is not lost if you don't have a 4.0/180!
Unfortunately, graduate GPA doesn't seem to count for a whole lot.
That said, in my esteemed opinion if you send out enough applications you'll probably get in to a mid to lower T1. If not, definitely a respectable T2.
Good luck with the application process!
