the university of hawaii at manoa offers full funding as TAs to students (i don't know of any who weren't funded that wanted/needed funding) who have enrolled in their physics MS program. they often wind up hiring TAs from other departments since their influx of grad students is generally small, so if you did get in (i actually have no idea how many applicants they get) you'd likely get a TA offer. the stipend is just above $15k/year, however, with no sign of increasing in the future; so you'd be living in an expensive city on limited means.
university of maine at orono is another (good for materials/surface science and biophysics with sam hess) that accepts masters students and funds most of them.
more generally - i too am looking for a funded masters program, and there seem to be a decent amount of good schools with direct admission into masters programs. some of the websites (i've only really looked at ones whose deadlines haven't passed...) have also said that they fund 'almost all' of their graduate students*; this i would take to mean PhD *and* MS students, unless i'm missing something?
