This is what I do for a new person in the hobby ( I own a store). I'll show you what I think will work best for you, because i want you to come back. If I have a used engine (Iknow the history) I'll offer it first. If your short of money I'll give you thirty days interest free to pay for it. I'll call the companies for you if you have trouble. And lastly I'll also will be at the field every Sunday to help you, because I want you to have as much fun as I do. And all this is free. Try that on E-Bay.
