Unranked/low ranked graduate programs in theoretical cosmology/hep-th or astro?

[Wheelwalker]

I'm applying for graduate school but am from a basically unknown state school. My stats can be found here: http://www.physicsgre.com/viewtopic.php?f=21&t=5735.

I am looking for a low ranked or unranked theoretical cosmology/hep-th school or a similarly ranked observational astronomy program with some interesting research going on to use as a safety or backup school. So far, I have Case Western Reserve and Tufts (is this a safety for me?) as a safety and would like one more school to add. Any recommendations would be very helpful.

Thanks!

Tufts is generally a very good school, but I don't know about their cosmology programs.
