Hi Rotorfan,
If the price of the Turbine Rotorway is between R22 and R66, it will likely be closer to the R44 or R66
The cost of training is somewhat constrained by the cost of purchase + cost of ownership and return an 'investor' wants on purchasing a ship and running it with a training organisation. I see this with EC120 too where in the US (due to the age & value of that machine) a flight org want $1600/hr for SFH and in the UK I pay @ £500/hr ($750) for an equally good, but lower value unit.
In the UK, the cost differential between R44 and H500 was only £50/hr ($75), so no brainer for me to start out on the H500. Then, when I saw the US cost and advantages of the FAA license I chose to complete in the US. The cost for me training in the US on a H500 is $450 (with a value of $350-400K), is the same as training in the UK on an R22 (£300).
R22 training in US is @ $300/hr...I don't think any org will give you turbine training for much less than $450 as the expensive risk as always with turbines is in Start-up and Shut Down (and for the reasons mentioned before)
This may be 'the least expensive new turbine bar none', (Norwitz, 2009), but if it will still cost more than an R22 and consequently so will the training costs.
Cost of turbine time is a problem for all of us that want to fly bigger and faster and I hope that the Rotorway does work out more econimical than other turbines to train on - just my experience, training on turbines in US and UK would indicate otherwise.
BTW. I like Rotorways and my flying buddies have said I can fly their one if I lose 60Ibs!!

..so it looks like i'm stuck flying the E120
Good Luck!
