I have PPL and it's great, but it's not much good if you have no money.
I'm not sure how much I'd recommend a loan. As keen as you most likely are to start, I recommend putting your energy into your collage degree to insure you're top of the class and most likely to get the big job after you finish. Then when you're raking it in, do your PPL.
If you're in collage and you do decide to get a loan, be sure not to drink it.
We laugh, but I've seen it done on more than 1 occasion.
I learnt to fly during my apprenticeship, so I had some income and was able to steer clear of loans.
