Just to add further weight to this thread, I completed my IR last week at Stapleford. Total cost (including charts, headsets and all the other misc items) was £42K from "zero to hero". Oh, this also includes the MCC course I've prepaid.
ATPL's full time via London met, hour building in the States.
When I started looking for training, CTC quoted £67K, so I feel I'm £25K in the black.
Please PM if you have any questions.
