radarcontrol,
I did my PPL with Multiflight, though it were over 3 years ago. You can pay bit by bit; thats the way that I paid since I funded my lessons from my part time job. I was happy with the training that I received. I completed my PPL in 52hrs, due to the British weather, and fitting the flying in around my A Levels.
The weather always seems to be worse at Leeds than anywhere else, but there again I have flown out of leeds with 20K vis, whilst on the other side of the pennies at Manchester vis was 5K.... Certainly if Leeds is a much more convenient location for you, do your training there.
