Hi SP,
As I said before, honestly the airlines really really don't care where you did you're PPL, it could be with Shady Joe Bloggs' School of Flying, no one gives a hoot, so I'd do it as reasonably priced as poss, be it here or abroad if financially worthwhile. Any local airfield should do the job quite nicely.
However, if you are thinking of Stapleford for commercial training then you wouldn't go far wrong in my opinion. I did my groundschool at Bristol GS (again excellent), then the flying with Stapleford. Good outfit, igood instructors, VOR on the field, Southend down the road for other stuff. And I paid a bit at a time when I was there so no worries about being shafted with all money upfront and the owners enjoynig Rio at your expense.
