Hi, I have a Stihl straight shaft line trimer, about 15 years old starts up straight away, never done an overhaul on engine or carby, it copes with long grass and fresh blackberry canes and assorted scrub. I have another brushcutter for blade work, red factory paint about 20 years old , do not know the brand name; it also runs well. I had a kawasaki about 22 years ago, also good put was pinched along with the family water pump. I have worked with some new husky saws, that ran well. Some cheap trimmers can be re-built quickly from second hand parts with the right skills. You also need to think who is going to use the tool, you would have to walk over my dead body to touch my 2 stroke engines! I can't believe my Stihl runs so well after all the hard work. Make sure you use the recommended line size; and take that extra time when using them on the job. Do not overload the engine. Take time to: sharpen blades; use fresh clean fuel; lube your cutting head shaft. Try contacting you local horticulture college or university; and ask contractors what they use. If I had the money I would grab a Stihl, straight shaft, mid range type, with the twin handle set up; able to take a blade, given that you have used such powerful saws!
