Well anything you buy from the states is a bargain at the moment due ROE! Maybe the FTO in question was the most cost effective option before the increase but were unable to sustain it due to increased costs?
It does not matter where you train lowest up front cost does not necessarily mean best long term deal. From experience I did PPL, IMC, Night and Multi abroad for a song but spent a lot once back in the UK on getting the standard of flying up to what it should have been and consequently paid more long term. Price should not always be top of the list.
