I don't know if it's the case anymore but several years ago disposed Ryan Ryobis were prolific and you couldn't give them away. I ended up accumulating 13 or so and threw most of them out when we moved.
I scored a good early build 1980s one with green plastic shroud with Tillotson carby that goes like a champ to this day, though gets hot and needs a rest after a while of leaf blower attachment duty which consistently labours it. I never use it for trimming any more as my full crank Mitsubishi powered straight shaft Kaaz performs so much better.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
