Mostly RV ILS, but this is partly because when flying in/out of the UK to Europe, you have to head for a Customs airport every time and most of them are bigger places.
If you were flying intra-schengen, there would be a significant # of nonprecision GPS approaches outside the UK.
As A&C says, Greece likes the procedural ones. I got a bit of a suprise when the radar controller at Hania LGSA gave me a full procedural VOR approach
I bet they don't do that with the F16s there; another 1000kg of juice burnt flying the outbound leg halfway across the thickness of Crete...
In practice, you head for an ILS every time you have a choice - even if there are GPS approaches available. Very very few GA planes have their IFR GPS approved for flying approaches, whereas any half decent IFR tourer can fly an ILS, on the autopilot, down to 200ft AGL.
