The magneto adds alot of weight, the way i look at it you get what you pay for, there are so many cheaper engines out there and many are also really nice and run well without breakdowns, even many of the cheaper engines also have the three crank bearings and that to me is a must and well worth it in the long run. Also look around as there are alot of nice engines out there different brands that are not real expensive and run well, look around for a second hand DA-50 you cannot go wrong with them engines, they have been out for years and is the best engine on the market today and has proven it over and over again, been in the winners circle now for many years as well, i bought the DA-50 and i would buy no other, but that is just me and i would not put down other engines, it is your choice and be happy with what you have.
