Oh, how I agree with those of you who are sick of hearing about 'priorities'. We have no TV at all, one car (and it's a Prius - fuel costs) and very few holidays.
Ok, our house is on the big side, but it's also on a main road and it's miles from anywhere. And it's falling down...
And yyy to those of you who hate people who drone on about bursaries. I BLOODY HAVE been laughed out of the bursar's office.
We will be in debt for effing EVER because of the fees we paid for ds and dd, and it was tbh a huge waste. Up to a point.
Here's my summative assessment. All personal. Your dcs are not my dcs and you are not me. 
On the plus side, DS did emerge with 12 A* at GCSE, but he was also severely depressed and constantly bullied. The school did pretty much nothing. Behavkour there was/is appalling. The school bus was a sink of sexual harassment and even assault.
He has just got offers from Imperial and Durham - turned down by Oxford, alas, but only by a whisker - and he is now at an FE College, which is where dd will and up next year. Ds has been incredibly happy at the FE college, much happier than he was at independent school.
DD is homeschooled - after 5 years in fee-payers - was bored to death a posh girls' school (exSam Cam) and is now 2-3 years ahead of her age group in four languages. She has lots of friends in reeneactor circles, and is on the whole very happy. She very reasonably wants to go to the FE next year, and it looks like this will be doable.
if I had my life over again, I would NOT send them to private school.
