Not cheap but you have to compare time life components. When most of the 22's one are limited to 2200h, most of the Cabri's one are in a range between 2000 and 6000h (main rotor blade, hub, swashplates). Operating both aircrafts, cost is quite the same.
Base price is 348 K$ 1EUR=1.28$
The 3 heavy blades rotor gives huge inertia and autorotation becomes a teen game, Fenestron provides good external security, crash resistant seats increase survival potential, fuel tank and circuit is ''F1'' made, plasma ignition relacing one magneto, auto carb heat.....
I'm not blaming the Robi's but all new technologies have been integrated in this new aircraft.
