Plus, if you get your PPL (or RPL even) you can build GF, nav (not with RPL obviously) and PIC hours that will count towards your CPL in a mate's aircraft, or one you can access a bit cheaper than paying the flying school.
Not so much an issue if you're going to go straight through, but if you take a break or run out of money partway through, it's a consideration.
Fee help and all that is OK, but you'll have to pay it back one day anyhow, so if you can get some cheap hours on the way through that's not a bad thing.
(PS GFPT has gone the way of the dodo with Part 61, now a flight test for an RPL, but once licenced you don't need flying school supervision, can sign your own MR etc.)
