Which state do you live in?
Reapplying depends on your application that got rejected and how the new one has improved. If the changes are significant (i.e. increase in MCAT or GPA), go ahead. It's hard to define a 'significant' increase, though.
With a 30 MCAT, the upper echelon of schools is hard to get into. There's kind of a limited group of reach schools for you, since the top schools are out (for the most part) and there aren't too many 'bad' schools, so there are a lot of schools left in the middle.
I'd recommend Jefferson (PA) and MC Wisconsin. They both have good Residencies (esp. Jeff). GW and G-town are solid, but very expensive. I really don't think there are too many schools that fit the bill as worthwhile reaches. In general, you can consider: RFUMS, NYMC, Drexel, Loyola, St Louis, etc. but they may not be considered worthile reaches.
