I have nothing against experimentals or homebuilts per se but, I have had three students in the last 18 months who had a Rotorway and a Safari. We use Bell 47's for training, the two Rotorway pilots bought Bell 47's and the Safari pilot went back to flying it. I have to say it looks very nice and it seems well built with a factory Lycoming engine. The problem they all had was with insurance. They could not get insured on the Rotorway or the Safari with anyone for any price. No problem with the Bells. I think insurance is important. I really could not fly anything that I could not insure.
Your landing area seems fine now in terms of size. Have you considered a Bell 47? $60,000 should get you a good D1 or G model.
