Funny thing about Saitos- as soon as you buy one, you want more. Not only do they run and sound great, but they are truly sexy. When I started in this hobby, I thought they were pricey compared to the 2-strokes, but once you have one, you will never want another "whiner" (2-stroke). I have a .56, two .72's, a .91, two 1.00's, a 1.20, and a 1.50. I really enjoy them, and they are a real piece of engineering brilliance. Form meets function.
