Financing?

[Xanthia Alysha]

I've never financed anything before (I do have credit though so I know I can get one).I'm wanting to finance my breast augmentation & I had a question.
It's going to cost me a little over $4300 and I was wondering if you could pay the doctor half of that and then finance the rest or if you had to finance the total lump sum & then you make bigger payments on the monthly payments to get it paid off faster.Or which way is better?
