</font><font color="blue" class="small">( Now for the weed wacker I have a Craftsman 6.75 HP that has been thoroughly abused. )</font>
Along with my cache of Stihl equipment which I keep at the farm I also have a $99 Sears model here at my house in metroplis, which is small so the trimmer only sees 10 minutes of use at a time. Little story about it, I had it a year and it just wouldn't start easily or run well. One of those 95 degree humid days when it wouldn't start I tossed it across the yard about 20 feet /forums/images/graemlins/shocked.gif and it cart wheeled end over end bending in the muffler and bending the shaft....well that was about 7 years ago now and it has worked fine ever since. Have never even done any type of maintenance to it.
Allot of units are good and generally you get what you pay for. I would buy from a shop that has been in business awhile, whatever brand they sell will be good and they will be able to get you parts if required. That is what it pretty much comes down to.
