I believe you can find good equipment with any of the major brands ; Husqvarna, red max, stihl, echo, shindaiwa and so forth.
I have owned a Husqvarna 323L string trimmer for 7 years and only changed the sparkplug once and adjusted the carb once. I run the stilhl synthetic oil and add stabil to the fuel. It cranks every time on the first or second pull. I like it better than the stihl. I operated a Shindaiwa for 60 hours per week on a road crew back in school and it was the best I ever operated. The shindaiwa had to have 2 shoulder straps it was so big.
I have a Husqvarna 450 chain saw, a 48' sears-husqvarna made riding lawn mower, and a 61" husqvarna zero turn mower. I am not loyal to Husqvarna. When I compare performance to price, I find Husqvarna to be a winner in the size equipment I purchased.
You can buy cheap equipment every year or buy good equipment every 10-15 years. I have found for me it is cheaper to buy good equipment.
