Alright guys, here is the deal, I need a string trimmer by monday and I have not really had the time to do the research. What do you recommend? Is a steel shaft absolutely necessary? I have an echo pe-230 edger that I am fairly pleased with, and that just has the cable drive, and I haven't had any problems yet. I want something good, because this is a tool that I use every day, probably more than my mower, lol. I also have no idea on price range.. I want to spend no more than 300, and if I can do one for 250 or so that would be even better. Please don't just get on here and say, "get this one, this is what I have and it is the best because I said so!" I want practical reasons why to get this specific trimmer. ALso, I tend to think the my pe230 is a hair underpowered, is this true for string trimmers too? I am thinking the minimum cc's i want is at least 25 or so, what are your thoughts on that? So here is a list of possible competitors (I don't want a four stroke either).... If you could give me rough guesstamations on prices that would be sweet!!! Also, I want something considered commercial duty, if any these are not up to the task don't be afraid to say it. Who has the nicest/most durable tap head? Can you swap heads between most of these trimmers? Echo SRM 260 Redmax BC250? Redmax BCZ400s Redmax BCZ500s Stihl FS80 Shindaiwa T230 Shindaiwa T260 Let me know boys, thanks.
