Public vs Private ?

I'm only a junior in high school, so this doesn't affect me immediately, but I wanted to know because I have a list of about 3-4 schools I am interested in for nursing. I was wondering though, is it stupid to pay big money to go to a private 4year university for a BSN?
Here's my list (all in Mass.)

Curry College - private, but very good program (100% pass rate on NCLEX)
UMass Boston - public
UMass Amherst - public
Mass College of Pharmacy/Health Sciences - private, accelerated 3year program

So, is it a waste of money to shell out $24,000 a year when I could get the same degree at my state school? Has anyone gone to a private school for nursing/was it worth it?
Also, your thoughts on accelerated programs...
Thanks so much
