German-Spanish (Hans is the boss) outfit that have had good reports on this forum (darned if I can find them though using the search facility

)
I may well be using them this summer for some hour-building - a/c capacity providing. When I spoke to Hans last summer, first impression was that prices weren't significantly cheaper than you'd pay in the UK (certainly compared to the US anyway) and you also need to bear in mind that you have landing fees to pay too. Good weather and interesting places to visit (Morocco anyone?) are big pluses though. Fog can be a problem in Feb/March time, and Spanish language may be an issue if you go off the beaten track.
May need to check on the JAA/CAA-approved bit though via the official channels - my understanding is/was that F-i-S weren't approved/licensed to conduct JAA/CAA training (this may equate to official JAA/CAA FTO-status), but this may well have changed. Worth checking out if you intend to do most of your flying back in blightey.
