Here is the order I vote in. Brison number 4. Just becuase I havent reall heard much about them. 3W 106 is number 3. I put it number 3 because they run very strong, when they are running. There are a lot of comments on how hard these engines are to tune and run. A lot of people like them but alot dont. Number 2 is BME. I pick the 110 over the 105 cause it makes quite a bit more power for the same weight and only 50 bucks more. You really cant go wrong with either one of them though. Both are as strong orstronger than the old 3w 100 and da 100. The reason I put them number 2 is I have heard a few customer service complaints and several people still dont have their 110 that they ordered last year. If i was to buy one, I would probably get BME cause they are more powerful, plus a lot of people dont like them or dont have them so I can get one and be different. I'M not worried about customer service on the phone, becuase if I have trouble ill just take it to Waco myself. Not a far drive. As far as being good at everything, DA is the way to go. They are like the cadillac. Very powerful and from what I hear there is no other company that has as good of customer service as DA. I think that is one of their big selling points. This is just my opinion. I dont have any personal experience with them but if BME went out of business, I would get a DA just becuase of what I have read on RCU.
