after hrs of research an forum reading I went an got a srm266t today an wow am I dissapionted! my srm225 is more powerful I think.....I ran them both side by side switching back an forth several times in tall grass. im taking it back tomorrow an praying ill get a refund so I can try the 100rx. I want this trimmer for ditch cleaning and it was struggling with common 12" grass. is there a better option for under 400$ im just getting started an don't have alota $ but know im losing time an money cleaning ditches with the 225. thanks
