Good choice.
Three reasons for training on the R22:
- You want the lowest cost
- There's lots around
- You plan to fly other Robinson products
Three reasons for choosing the S.300
- It was developed as a training helicopter
- It has a more sophisticated design
- It has greater active and passive safety
Remember with the later 300s there are three models - CB, CBi and C - The 300'C' being the best.
Interesting Tim should mention the EN 480 Turbine. I learnt to fly in a 300C, but now regularly fly an EN 480B. However, for fun, I still regularly fly a 300C.
I can tell you, the 480 is much easier to fly than a 300 or R22. If learning to fly a helicopter quickly was an issue (not necessarily sensible) then I would recommend the 480.
