Some very good advice here . I have owned all of the types mentioned ( apart from Robbo,s or 120 ) and agree with all said , but would add that the 206 is on a steep downward slope re price . ( look at 505 thread !) . If it were me I would buy a very cheap 206 , or better still sfh one and put an order in for a 505 now . And if you go EC or AS be aware of engine costs as turbomeca can charge like a wounded Rhino !! Very good engines but go PBH if you possibly can . Enstrom lovely and easy for a beginner but slow slow slow !!!!
