If you get a TA at Rutgers you get full tuition remission + ~25k/year teaching stipend (you have to teach a class each semester). About half an incoming class gets a TA, others can get a combination of part-time lecturer positions/money and scholarship grants to cover costs.
I know Cornell and Rutgers both offer full tuition remission and living stipends (Rutgers' stipend is actually around 24k, but only those who get a TAship get the deal).
I would recommend looking at Rutgers - many abstract painters in the student body and faculty - plus it's close to nyc and there is generous financial aid for TAs (ie full tuition remission + living stipends).
