I am coming full circle with my battery stuff. I have the Milwaukee 18v and it has made me money. With that being said, I am getting very close to needing to replace my batteries, and that's going to be a bit of a punch in the gut. This issue for me is, I have my 4 year old trimmer that needs new batteries. Do I invest that kind of money in batteries, for a trimmer that old? For me, I just can't do it. My batteries are on their last legs. When my 9AMP'ers go, I'm getting another RedMax, and will be all gas for trimmers. I have plenty of Milwaukee tools with the 5 and 6 amp batteries, and I'll use those in the blower.I looked seriously into battery models, with the Ego and Echo lines being top choices. Ultimately, going to just buy an Echo gasser this season and maybe revisit again next year.
As someone who's run that battery stuff for a few years, I am in complete agreement with your decision.
