get the 480B and if you are heading to hot weather get the hot kit for not much more.
people tell me the 206BIII does not quite do what it says on the tin, a lot extra loot for something that wont lift much more than its predecessers. and lots more running costs.
so for leisure an cool climes an 206A might be OK but I'll bet its running cost will line up with or be more than the 480B. Go for a fly in one, they are magic and easy. You will be amazed at the fuel economy when you wind back the airspeed a bit as the three bladed rotor just seems so efficient and smooth as others have said, be sitting down when you read the retirement life on the blades.
480B autos, well was there one?
never seen a 66 and not looking to see one anytime soon.
