At that price you could afford to replace it every year for the next five and only start matching the intitial outlay of a Huski branded saw. I bought an el-cheapo brand GMC whipper Snipper almost 8 years ago from the big green shed. It cost me $99.00 at the time. I've never done anything to it, not even a spark plug. It just died a last weekend, the drive shaft snapped. I was pretty impressed with the life of that thing.
If it's made by Huski and they cover the warranty, then I think I will head down to Masters at West Gosford and buy myself one. Nothing to lose I think.

V8100 for the heads up.
