RedBullGaveMeWings - I know one instructor that works @ CAVOC Aviation Training. A young guy that I've met when he came to Poland to do his training. I'm sure he would not be involved in a school that does not provide quality training. If I remember correctly they are the second aviation school (after WizzAir) in Hungary that got an ATO certificate.
I hope someone that trained there will be able to provide more details.
