I don't know anything about Shindaiwa but this is what I know about Stihl. I think a better choice is the FS 80 instead of the FS 85. Here is why. They are the exact same machine..same engine, displacement, power, etc. The only difference is that the FS 85 has a solid steel drive shaft, where as the FS 80 has a flex drive cable. Both drive shafts have a lifetime warranty and you have to pay a premium for the solid steel shaft. Check with your dealer, you can probably get the FS 80 cheaper. This is the machine that I use and could not be happier with a trimmer. I'll buy another one if this one ever wears out.<p>----------<br>Bryan..Heartland Lawn Care<br>heartlandlawn@hotmail.com
