Also keep in mind that non-mstps tend to be smaller programs. Some are much smaller. For example, one "low tier" school I interviewed at had 60 people interview for 2 slots and had an instate bias. The MSTP I got accepted to interviewed about 100 people for 12 slots. Which program do you think is easier to get into?
If you are set on finding non-mstps, then in addition to the ones already mentioned I would also apply to uconn, buffalo, Nebraska, Penn state and RWJ/Princeton. At least when I applied, they had a reasonable amount of slots per year (about 5), were strong in certain fields and seemed to be on an upward trajectory.
