From what I read on this site a BS plus an ADN would not be the same as a BSN. There might be master's programs that would consider the BS, but you'd still be an associate's degree-level RN.
I 2nd checking out West Chester- affordable and when I called the HR department at Presbyterian (b/c I got in a flame war about whether there were hospitals that would only take BSNs) a couple of years ago, the woman I spoke with said West Chester turns out really great nurses. I didn't apply b/c they want all your pre-reqs done before you apply and everywhere else I was interested in would let you apply with some still to go. But if I could have applied while finishing pre-reqs I definitely would have.
I'm starting Drexel in the fall. They don't offer financial aid for ACE students other than loans except for a scholarship
that you are apparently allowed to apply for near the start of the term, but the scholarship is geared towards minorities in nursing (so I don't know if it's something I'd be eligible for). Penn is supposed to be excellent with financial aid and from what I could gather from the open house I went to, they are really a supportive environment.
You can also search on the boards for opinions from students- those schools
are talked about a ton here.
