The experience we had in our school here in Brazil was always with the 300 and it's a nice machine, very reliable and excellent for training. However from a year from now, since the Sikorsky ending process for the 300, it has been very difficult to find spare parts and the school has now moved over to Cabri as a new project and spare parts availability. Have a close look at Guimbal and I am sure you will love this new trainer! The R22 is cheaper, but for quality training purposes, I understand the Cabri is a better choice.
