Ryan,
Welcome to PPRuNe,
I have no personal experience of any of the integrated schools, so I can't advise you on whether Cabair are better or worse than any of the others you mention.
However, you suggest that keeping costs down is an issue.
If you were to do a modular course, you would finish with exactly the same license, in a similar timescale, with more flying hours, and - potentially - a large cost saving. I won't go into all the advantages/disadvantes here, because it has been discussed many many times before - do a search and you will find plenty of information comparing the two types of course. Not that there's anything wrong with the integrated course - but don't tie yourself down to it at this early stage.
Also, before you get too involved, have a trial lesson if you haven't done so already, just to confirm that you really do enjoy controlling an aeroplane. And, most important, get down to Gatwick and have a Class 1 medical, because if you can't get the medical then everything else is a waste of time and money.
