I know i never see any words of love for tanaka, but i love them. I have one, 7mm shaft driven, 41 cc motor (I think, i am not a mechanic, use my dealer alot) but i know it kicks but. Here is my modo. BIGGER!<p>With the biggest most comfortable trimmer in your hands you can never run into the problem of not having too little power. My new trimmer is gonna be 18 lbs. Who cares? It just means ill get stronger. My old one, which still runs perfectly, is 15 lbs. Tanaka is the brand for me. I used to use echo, but they have nothing that interests me with the power i want. <p>Second note: Dont get the bullhorn models. I personally cant stand them. It makes it very difficult to line trim an edge. Go to your dealer and ask for the biggest trimmer (NON bull handle) to demo. Try it. Better to have too much power than too little. AND, with the big models you never have to upgrade like i hear MANY of the other postee's doing. Know what i mean. <br>Have a good one ya'll.
