I have a small yard, I bought a husquvarna straight shaft unit...
Growing up, my parents had various curved-shaft units, the kind that spin the head so long as the engine is on, and then speed up with the throttle. The higher end units like my Husq. have some kind of clutching so they dont spin all the time.
For a small yard with lots of detail trim work, I dont want to have to be spinning up my machine too much. I could do the whole yard fast and easy on the curved units growing up without barely touching the throttle for much of it. Maybe not the best for a 2-stroke engine, but 10 years was never an issue.
So Id look for a good brand, whether stihl, husq., echo, etc., but I'd look for a curved shaft model without the clutching for a small yard application. Id see if I could find a shop that had floor models that you could try.
My Husq. does start like an absolute champ every time, as does my echo leaf blower. Really great in that regard.
