You can get a "bad" one of anything. There is nothing wrong with Magnum engines. I currently own and run 5 magnum 4 stroke engines, and they are all superb engines. Within my immediate family, we have no less than 15 magnum 4 strokes, and NONE, I mean NONE of them have caused us one minute's trouble. We also have over 10 saitos within the family. Three of them have been returned for service. I will probably not buy another saito. I simply love the magnums. You lose a bit of power over the OS and saito, but you always know they will perform for you!

Anyway, go whichever route you want, I would just hate for someone to stumble onto this post and get the wrong impression about a quality product.

Let the flaming begin....

BTW, to help you out, I agree with the saito .56, but also don't rule out the saito .72 or magnum .70
