I've owned and used many string trimmers, $300+ husqvarnas, echo, etc etc, my favorite one by far is still the 30cc 4 cycle Ryobi powerhead which I also have almost every attachment for which is nice to sometimes only have to worry about one engine's maintenance.
At 30cc, I think it might be the most powerful 4 cycle powerhead/trimmer. I don't care about what comparisons says etc, I see no drop in performance that a 4 cycle less rpm/zippiness than a 2 cycle. And 4 cycle has more torque.
vs 2 cycle, it's quitter (I wear ear protection anyway but it's less of a nuisance to others and it sounds cooler, more low pitched like a little quad or something instead of the common annoying ass trimmer sound), no mixing gas and oil = cheaper and easier to run and cleaner for the environment and less fumes for the operator, parts are easy to find and replace on the Ryobi although the latest models have no L H screws on the carbs (?), heavier but it's better exercise.
I got like 4 of these off ebay for like $40 each shipped, some brand new, others are like-new returns to Ryobi which third party sellers resell as-is untested and usually all you have to do is fill with gas and it runs like new, and some of them include the ez wind type bump heads from the previous owner who returned it. Sometimes they just need a carb clean or just some starter fluid or something simple like a shut-off wire is disconnected hence the previous owner returned it to Ryobi.
Overall a very good machine.
The newer models have no L H carb adjustment that I can see but they have a foam air filter whereas the older models have L H screws but no foam filter but you can just add a filter I would assume it would still run good even though Ryobi purposely omitted the foam filter for some reason.
