I agree with fhhuber. Saito has a great reputation. The engines will also run FOREVER properly taken care of. My 120 is at least 10 years old, and it still runs despite the poor tuning by it's first owner. He had it 2000, yes 2000 rpm too lean. I'm not yet sure why. It still runs great though, and all its needed were some new bearings because the old ones didnt get enough oil when it was running lean.
