Well, since Ninja is tagging this, and since I have abused him alot. So, I guess I'll add something.
For me, it was easy. I used my existing lender for my law school loans (accessgroup) and print out some forms from the website and send it in. That's it and the checks started coming. You can have the check distributed four times. Instead of getting 20K say in May when you graduate, you can get it say 5K in May, 5K in August, 5K in November and 5K in February, that way, you don't have to pay interest on the 20K from the start.
I am not sure about how hard it is to get the loan, with co-signor and all that. I have a great credit score and I had no doubt that I will get the loan.
