Take care with a cheap Duchess. I own a Duchess and have flown a few on the field at BK. The old saying you get what you pay for has never been more accurate then with the BE76. As Fine-Green Said (he sounds like he has paid the price in his life) It's hard to run a duchess at a price under around $250 and make a cent. Thats given that nothing breaks. Parts are $$$$$. Thats if you can even get them. I had mine on line for a while before i relised that it does not pay) Going to give the charter seen a bash now to see if i can break even.
As for Schools. I can recommend Schofields (Who now have a new duchess online( Not mine) ) Price is more then fair and the staff have a good attitude.
I think Jeff Daniel and Peter are the guys there that can do Inital ME. Jeff did my training and he is great.
Good Luck.
