I have heard anecdotal evidence that St. Thoams grads do fairly well in Broward and Dade counties. I've heard of several grads working for both DA offices, and many PDs. As for GREATBIGLAW, I really don't know. Are they giving you any money? If so - actually, in either case - be aware of the fact that their curve is quite brutal (me thinks about 2.6), and this leads to a high number of students losing their money after first year... and to even more students being shown the door permanently.
Take that for what its worth, but like any law school, if you are determined, work hard and know what your getting into and what your realistic options are for after grad, I think you would do just fine there.
