I have used the Stihl weed eaters for quite sometime when I was working and I own one the F 90. If well maintained they will last and last they are really low maintenance. I got huret and am disabled now and have trouble handling it I was looking at checking on the weed eater with the wheels. I just read somewhere that they even make wheels that you can put on your own this would be perfect anyone know where I could begin searching for a set any suggestions would be greatly appreciated thanks Rick
