Choosing the 5105 was based on comments I read here and on another site. I used to have an 029 farm boss ,but I let it go after I purchased the Dolmar. My dealer is not to far away and that helped sell me also. I'm saving my money for the 7400 now. That will be a near perfect combination for my firewood cutting. My friends really like the 5105, I have to tell them I'm using it this week so they don't borrow it all the time.
