I did ($25k/year difference btw this and the other school), and many of my classmates did too. I am so glad I did.
I'm doing a healthcare shortage area repayment program after my residency, which will basically erase my debt....but even if I weren't going to do that, I'd not hesitate for a minute.
You'll be able to pay it off either way, but you won't get 4 yrs of your life back.
If you really loved the other school seriously almost as much, that might certainly make it a harder decision. If that's the case, make a list to compare the good and bad things about either choice.
But when you go to make your decision, consider where you want to spend your time more than where you want to spend your money.
