Look at a Magnum/ASP (same thing) .91 RFS 4-stroke ($129.00), or a RFS 1.20 ($165.00) from www.hobbyking.com. They run great and are as durable and powerfull as an OS or Saito. They are an OS clone...

If you want to throw more money at a motor to make you "feel better", then buy an OS or Saito or even a YS (most powerfull)... I do not think that you'll be buying a better motor though, but you might be one of those "I feel better now since I spent 2 to 3 times" more money on my motor...Good Luck..!!
