Was gutted when the flying school put the price upto £182.00/ hr in a 172. Personally I think that's a bit steep requiring at least another £4500.00 to finish!!!
If you can spare a couple of weeks - why not just pop over to Florida and complete the course over there? Ab-initio to PPL is around £4,500! You'll be able to take the hours over and complete in the much more reliable weather environment over there - then come back to extortionate rental prices
Just give the various JAA schools a call and ask them how much for the completion hours you think you'll need.
