Hi all, I'm in the market for a new string trimmer for my home. I currently have a Ryobi 12v battery trimmer that came with me from my old house and I don't think it will be enough for what I have now. I need to be able to trim, cut some open areas, and edge some plantings. I have a gas edger that I use for my sidewalks and driveway. I'd like a gas model, I don't care if I have to mix oil and gas since I do it for my blower, low vibrations, and maybe even a way to hold it with a belt. I tried the Troy-Bilt TB475 and I didn't like it. I thought it had too much vibrations, the engine didn't run real smooth, and my elbow would get burned from engine heat. What string trimmer would you recommend and why?
